I totally support that $x can only be a local variable and $foo::x can
only be $::foo::x.
I've been bitten a few times by having a "local" class name shadow a
more global one. E.g: Given there is a "bar" class from the module with
the same name. When adding a local modificator class "foo::bar" in the
"foo" module, the name "bar" suddenly has change meaning throughout
"foo" without any way to notice, except for super-humanly code review
and weird breakage.
I sometimes use very local defines like this:
class foo (...) {
define helper(...) {
# ...
}
helper { $ary: foo => bar }
}
I guess those could still fall under "local" references as long as they
are defined within the braces of the surrounding class. Perhaps external
reference to those should be forbidden anyways ;-)
