Re: Syntax, expressiveness and the beauty of Tcl

2+2 -> x

As far as I know, this came from POP-11. I've never seen it elsewhere.
And, as I've noted before, it's a good fit with Tcl syntax _iff_ you
use "->" as a synonym for ";" with the proviso that the scanner will
generate the appropriate "set" after scanning ahead to eol or the next
";" to pick up the variable name. That is, the above is simply
understood by the scanner to be shorthand for "set x [ expr 2+2 ]",
the same way it now understands $x is shorthand for [ set x ].
