[MetaCPAN] GET-ing a module by name Case-Insensitively

[Ævar Arnfjörð Bjarmason]

Are CPAN modules themselves case-insensitive? I wonder if PAUSE allows
foo::bar and FOO::BAR.

I doubt that such conflicting modules exists though, but it's worthwhile to
consider what this proposed metacpan API should do in the event of a
collision.
