Too much to type, perhaps we can choose some Unicode brackets, or some combination, similar to the normal brackets:
«: :»
«[ ]»
«| |»

and assign them to the keyboard near the << >> brackets.

LOCAL { z a } { 0 1 }

LOCAL { a b c d e f g ... } 0 @ Assigns to all variables the value of 0

This is the same grammar I proposed but accepting lists, it can be done.

In place of
0 1 -> z a @ IN (infix notation)

Existing syntax has to remain untouched for compatibility, so the -> operator will remain the same. The old syntax is good when it's used at the beginning of a routine, it shows clearly what the arguments are, I like that syntax.

I don't know what you mean by static vars, if you mean "compiled" as the manual calls them, they don't exist in newRPL, they were just an artifact of how old RPL worked more than a feature of the language.
