[unset] Memory optimization idea

It occurred to me that there are a lot of functions (both native! and mezzanine), even with REBOL/Base, that are never used in my scripts. I sometimes 'unset the larger of these to minimize REBOL's memory footprint, which got me to thinking that it might be possible to create a 'func to do this for me. The logic would go something like this: pre-unset funcs: obtain a list of all globally defined functions (use 'what as a template) script post-unset remove-each from funcs where func appears in script remove-each from funcs where func appears in funcs/mezz foreach func funcs [unset 'func] unset 'pre-unset unset 'self recycle Which should work so long as native! func's don't depend on other func's (native! or not). If this concept works, it could then be extended to other (eg. VID) words so long as the script does not create dynamic references (which is rare for non-user defined words in my scripts at least). What I was hoping is that there might be an easy way to answer the question, "Which words in the global context are not being used, and can they be unset safely?". Comments? Regards, Ashley<

Hi Ashley, AT> What I was hoping is that there might be an easy way to answer the AT> question, "Which words in the global context are not being used, and can AT> they be unset safely?". The best way is to get the SDK and only include the parts you need with the kernel of your choice. Barring that, I think the savings (aside from VID stuff--use Core or Base if you don't need it) is not worth the effort. "not being used" and "not being used _yet_" are very close but quite different. :) Please let us know if you've done any measurements to see how much memory you save with your efforts! -- Gregg
