To add a little strangeness; for your third proposition, on v5.10 Linux I get: 

Name "blah::a" used only once: possible typo at -e line 1.

but I don't on v5.26 Windows :)

All I can say is that with B::Deparse the package prefix seems to be removed, 

perl -MO=Deparse -wMstrict -e "BEGIN { *::x=\$a   } $x++"
...
BEGIN { $^W = 1; }
use strict;
sub BEGIN {
    *x = \$a;
}
$main::x++;

The output is exactly the same if I add package main; before setting *::x. (Also it replaces the $x++ by $main::x++, which would actually be valid code...) This might just be an optimization gone wrong?
