- default ansi color output - toggle with 'colour on' and 'colour off'
- experimental functional/pattern-matching language features. (will not be performant until more work is done on script compilation)
e.g.1 basic pipeline with 2 segments
`var_pipe_output.= var_list.= list a b c |> string toupper`
e.g.2 basic pattern-match multi-assignment to variables x y & z

e.g.1 basic pipeline with 2 segments
`var_pipe_output.= var_list.= list a b c |> string toupper`
e.g.2 basic pattern-match multi-assignment to variables x y & z
`x@0,y@1,z@2.= list a b c` equivalently: `x@,y@,z@.= list a b c` or even `x@,y@,z@= {a b c}`
`x/0,y/1,z/2,zz/3.= list a b c` is similar - but the use of forward-slash instead of @ will not produce a mismatch if an index is out of range.
where .= indicates following arguments form a command, and a plain = accepts only a single argument as a value
The diminutive case of this is `x= "something"` as equivalent to `set x "something"`
Assignment operations and pattern-matches are slightly optimised to bytecompile, but are unlikely to compete with raw Tcl commands performance-wise.
e.g.3 destructuring pattern-match. Get value of key 'k1' from last item in a list of dicts.
`x@end/@@k1.= list {k1 aaa} {k1 bb}` returns bbb

There are many more pattern-matching features yet to be documented.
- easy execution of externals commands with return of stdout, stderr and the exitcode of the process
- `run <comand> ...`
- `run <comand> ...`
(return exitcode of process - and allows process writes to stderr/stdout to appear in console as they occur)
- `runout <command> ...`
(return stdout of process - no output until completion)
- `runerr <command> ...`
- `runout <command> ...`
(return stdout of process - no output until completion)
- `runerr <command> ...`
(return stderr of process - no output until completion)
- `runx <command> ...`
(return a dict of stdout stderr exitcode - no output until completion)
- namespace browser (contextual - allowing running of commands within the active namespace - analogous to 'cd' for directories)
- `n/` - display child namespaces of current namespace (alias `:/`)
- `n/` - display child namespaces of current namespace (alias `:/`)
also `n/ <globpattern>` to restrict output
- `n/ <childns>` - if the argument doesn't contain glob chars '*' or '?' - attempt to switch to a child namespace of that name. Analogous to `cd <dir>`
- `n/ <childns>` - if the argument doesn't contain glob chars '*' or '?' - attempt to switch to a child namespace of that name. Analogous to `cd <dir>`
list any sub namespaces of the namespace we just switched to.
- `n//` - display child namespaces and commands (alias `://`)
with colourised indication of type such as proc,alias,ensemble,imported,exported where possible.
- `n//` - display child namespaces and commands (alias `://`)
with colourised indication of type such as proc,alias,ensemble,imported,exported where possible.
(renamed aliases and builtins and commands loaded from binaries will appear unmarked)
- `nn/` - move up one namespace towards root namespace '::' analogous to `cd ..` (alias `::/`)
- `n/new <somename>` - create a child namespace called 'somename' and switch to it in one operation. (alias `:/new`)
- cross-platform alternative to cd & ls/dir without invoking child processes. Display colourised listing of dirs and folders - with vfs indication.
- `d/` - list current directory (alias `./`)
- `d/` - list current directory (alias `./`)
also `d/ <globpattern>` to restrict output
- `d/ <subdir>` - switch to subdir and list contents in one operation
- `dd/` - move up one directory and output listing. Roughly equivalent to `cd ..` followed by dir or ls (alias `../`)
