Then it's a false rationale. When you export globs[0] it's only a shallow copy - so the new glob is created in the symbol table, but all the glob slots remain in the same location e.g shell> perl -l - $foo::bar = "a string"; *bar = *foo::bar; print $bar; $foo::bar = "a new string"; print $bar; print \$foo::bar; print \$bar; __output__ a string a new string SCALAR(0x1012f6cc) SCALAR(0x1012f6cc) So as you can guess this just isn't memory hungry, so the reasoning for not exporting globs shouldn't be because of the memory. Now namespace pollution is another thing, but I reckon if your subs are relatively unique then it's not much of an issue, but then again it's not much of an issue to fully qualify the subs (assuming they're in their own namespace).
