[REBOL] Re: Limit on Globals?

Hi Tim, Ryan,
Just a couple of quick comments on 'global' words (those listed in first
system/words).
1) Every token in the source code which scans as a valid REBOL word is added
to the global words. It makes no difference whether the word occurs in the
local context of an object. In fact, even asking if a word is in first
system/words will cause it to be added because the code is scanned and
loaded before any evaluation occurs.
2) There is no way to remove global words. They accumulate in any REBOL
session until the limit (currently 4094) is reached.
3) It is good to remember that a given word can be used in many contexts,
referring to a different value in each context. A coding style which reuses
variable names is less likely to result in reaching the limit on words.
