Hi Marcus,
I think the confusion is not on semantics, but on the discussion level. I
have absolutely no doubt that it is impossible to disable override of
global identifiers by local identifiers in Pike as it currently stands. I
fully agree with your reservations that this would create
Well, the context here is the language Pike, so please realize that
when talking about global identifiers, this refers to the Pike
concept of global identifiers, unless otherwise specified. And I will
assume that the same goes for when someone talks about classes and
signatures.
I think there is a sematical confusion here. global identifiers are
those which are not (conceptually at least) part of any class. Like
time for example. Or MIME, or Protocols. Adding a new global
identifer (by adding a new module, for example) does not change the
signature of any existing

You probably want to explore the #pragma strict_types.

Why is it strange?

ok, so in the scope of this function
time is an actual parameter of type int.

you can't have both a variable and a function named time.
when you create a local variable (or any other symbol) it overwrites the
global one.
you can still access the time() function by using predef::time();
