I'd let the program worry about that.  Most shell expansion works.

$ perl -wle 'print join " ", @ARGV' -- --foo={1,2}
--foo=1 --foo=2

Its only ~ expansion that doesn't and that's easy.

	$path =~ s/^~/$ENV{HOME}/ if defined $ENV{HOME};

You are wicked and wrong to have broken inside and peeked at the
implementation and then relied upon it.
