I agree; with both of you. :) For the most part, we can just ignore it and be happy that REBOL does what we want it to do, but there are those times...and when they arrive, we need to understand what is happening. Thinking in different terms is the hard part. For me, the big hurdles are: 1) Everything is just data (that may be evaluated at some point). 2) "Definitional Scoping", that is, being aware of where something is defined with regards to context. 3) Everything is data. There is no "code". 4) Remembering that just because you see x someplace and x just a short "distance" away doesn't mean they're in the same context. 5) Oh yeah, everything is data. If you can remember that everything is data, I think it makes it easier to get into the mindset of thinking about context, where things are defined (because that usually implies some kind of context), etc. REBOL makes me write (and read) code in a manner *very* different from other languages. -- Gregg
