`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.= 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.

Assignment operations and pattern-matches are slightly optimised to bytecompile, but are unlikely to compete with raw Tcl commands performance-wise.

There are many more pattern-matching features yet to be documented.
