[REBOL] Re: To do or not to do?

Hi Ladislav,

I know. The limit is bind which does not bind to any but word! datatype! I do not understand why RT have not made bind more general (any-word!) If the starting word was [:z] noone can convert it to set-word/word/lit-word while preserving binding. It is a bad hole in Rebol.

What i do not understand is why 'to does not preserve binding. I understand that some values passed to to-word have not an original binding, like string, and that only the global context can be extended. But i think that is difficult to remember that code like this: a: 50 use [a] [ a: 3 print :a print get to-get-word 'a ] gives as result 3 50 It can generate subtle and difficult-to-catch error. Your /context should return an error if the word is not already defined in the context - this should be true also for global context. For ortogonality and block contexts (use/func) i think that the sintax should be: to/context set-word! 'word-in-a-context like with bind (and an implicit bind is exactly what we want). --- Ciao Romano
