In python there is eval() which evaluates and there is exec() which executes The difference is that one calculates a value which it returns , the other executes code. Personally I find "do it" very good choice because it makes clear what you referring to , in contrast "evaluate" and "execute" can mean different things under different context.

In general I banned evaluate from the book vocabulary because people think that this is slower. I saw teachers writing that smalltalk is interpreted and java compiled :). I use execute.

Mostly I take for granted that "DoIt" has always been the way to evaluate things with Smalltalk, however I find it awkward to use in writing a tutorial. Some examples... * After saving, select "Grid new" and "DoIt" -- this sounds awkward, and even that you might need select the latter as well. * After saving, "Grid new" DoIt. -- doesn't read nice * After saving, DoIt to "Grid new." -- worst of all
I'd feel better writing something like this... * After saving, evaluate "Grid new". but "evaluate" is not an item in the menus. I think actually many people talk this way with the implicit convention that "evaluate" means "DoIt".
So first, does anyone have a good way to compose sentences using "DoIt". Second, how evil would it be to change the menus from "DoIt" to "Evaluate" and so avoid the implicit convention.
