From @cpansprout

The bareword :​:CORE​::foo is deparsed as CORE​::foo, which is a syntax error.

$ perl5.16.0 -MO=Deparse -le 'print :​:CORE​::foo'
BEGIN { $/ = "\n"; $\ = "\n"; }
print CORE​::foo $_;
-e syntax OK

$ perl5.16.0 -MO=Deparse -le 'print CORE'\''foo'
BEGIN { $/ = "\n"; $\ = "\n"; }
print CORE​::foo $_;
-e syntax OK

The same thing happens with CORE'foo

$ perl5.16.0 -MO=Deparse -le 'print CORE'\''foo'
BEGIN { $/ = "\n"; $\ = "\n"; }
print CORE​::foo $_;
-e syntax OK
