Keeping := Franciscan in its simplicity would make it easiest to implement, easiest to explain, AND avoid all sort of confusing cases where the distinction between := and = would otherwise be confusingly nonexistent. It would also make it most effective because it always means the same thing -- "assignment to (already-existing) nonlocal". This is much the spirit in which I'd forego the idea of making += etc access nonlocals too, though I guess I'm only -0 on that; it seems simplest and most effective to have the one concept "rebinding a nonlocal name" correspond in strict 1-1 way to the one notation := . Simplicity and effectiveness feel very Pythonic to me.
Sounds good to me. Question: what does this do? def f(): def g(x): z := x g(3) print z return g g = f() print z g('foo') print z That is, in the absence of a pre-existing binding, where does the binding for := go? I think it should be equivalent to global, going to the module scope. -- Aahz (aahz@pythoncraft.com) <*> http://www.pythoncraft.com/ "It is easier to optimize correct code than to correct optimized code." --Bill Harlan
