Reserved identifiers, was Re: Thoughts on moving towards ANSI

[David Collier-Brown]

  At some point the compiler-writers are going to have to start
thinking about known (often partial) solutions to the namespace
pollution problems of simple languages like C. (and PL/1, lest
anyone think I'm being snarky with the use of "simple").
  Several of these are
	1) making unnecessary names disappear
		a) the C "static" keyword
		b) the Multics "binder"
	2) making all names unique
		a) class.element or class_$element
		b) user-defined prefixes 
		c) name: composed: out: of: whole: calling: sequence:
	3) explicit namespace-selection
		a) with x; use x
		b) invoke x
		c) import x from y
	4) controlled vocabulary
		a) the following 5280 words are reserved...

  I recommend against the last.  Considering the origins of C, I'd
suggest re-raising the idea of a binder once again.  I once wrote
one for a linker which produced almost-ready-to-run code, and found
that all I had to do was remove external-symbol records...
