[PUGS] 'is export' trait

[Garrett Rooney]

I might have this wrong, but isn't the 'is export' trait on a subroutine 
supposed to indicate that it's exported into the namespace of the code 
that uses or requires the module?  That doesn't seem to be happening 
right now.  Well, it is happening, but it's also happening for 
subroutines without that trait, and that seems wrong.

For example, if I have the following files:
Foo.pm
module Foo-0.0.1;
use v6;
# note the lack of 'is export'...
sub bar {
  say "Foo::bar";
}
foo.p6
use v6;
use Foo;
bar();
I'd assume this should be an error, since bar isn't exported, but it's 
not, running the code prints out "Foo::bar".  This is even the case if I 
define another 'sub bar' in foo.p6, the version from Foo.pm is still called.

Am I missunderstanding this, or is it a bug?
