Re: Syntax, expressiveness and the beauty of Tcl

That all looks very weird and complex. What about a simple and strict
polish notation, like in LISP:

proc + {a b} {expr {$a + $b}}
proc - {a b} {expr {$a - $b}}
proc * {a b} {expr {$a * $b}}
proc / {a b} {expr {$a / $b}}

set res [+ [* 7 8] [- 8 9]]
55

Every operator is a command as well and it is compatible with the rest
of Tcl (although it will be even less familiar to the majority of
programmers)

TIP #174 (http://tip.tcl.tk/174) is being voted on this week.
It provides exactly the Cambridge Polish (not RPN, the "reverse"
in RPN indicates that the operator comes *last*) notation that
you request.
