Are you really talking about "scopes" in the formal language sense
here?
Yes -- does Objective-J generate lambdas in other functions which
refer to lexically scoped variables in enclosing functions. At least
one Ajax library I know of (EXT) does this using eval.
I think they only care about new Function() constructed functions. At
least, this was the focus of the discussion I had with them.
For what it's worth - they only really need the ability to set the
name once, not to mutate it multiple times. So if making the property
mutable for everything seems distasteful, I think an alternate
function constructor that lets you provide a name (which is thereafter
immutable) would be an adequate solution. I would prefer that to
sometimes having a read-only name property and sometimes not. For
example:
Function.create("[Foo bar]", "param1", "param2", "code(); goes();
here();");
This would allow us to retain the name "anonymous" for functions
created without providing a name.
