Re: [Python-ideas] Syntax for late-binding of arguments [was: Default arguments ...]

Le Sat, 16 May 2009 00:33:20 +1000, Nick Coghlan s'exprima ainsi:

It's not the object that is being marked as special: it's the expression to create the object. The new syntax is about delaying evaluation of that expression - the parameter itself is perfectly normal, as is the object that is ultimately bound to it. But moving the default argument evaluation to call time instead of definition time - that's special.

I rather agree. Then we should mark the binding sign '=' as special (not the parameter / the object)! E.g. def f(arg &= []) or def f(arg @= []) I looks a bit strange, but we have augmented assignment already. Denis ------ la vita e estrany
