The same way it does when it sees a normal sub?
I know, late binding and all that. But when you think about it, a lot
can be done to simulate the conditions otherwise. For example, with a
definition like this:
class Foo {
method bar($self: $baz) { ... }
}
And a call like this:
@b=$foo_obj.bar $baz, $quux;
Where we can see *at runtime* that $quux is too many arguments, we can
just append it to the end of bar()'s return value. (This would only
happen when there were no parentheses.) Similarly, with:
class Foo {
method bar($self: HASH $baz) { ... }
}
And:
%b=foo_obj.bar { baz() };
We can call the closure and construct a hashref from the value.
