Isn't that a valid index into the array? Or is that

Hi all.
I'm trying to get quoting interpolation to work, which means I first have to

In Perl 5, as far as I can see, the delimiter of quoting constructs (whether
it's "", '' or qq ) is searched for before the string is parsed. This
means that, for example,
