in reply to How to export hash references

Package Foo;

This isn't valid. In Perl, package is all in lowercase.

Your actual problem (once that's fixed) is that you are not escaping the dollar symbol.

$ perl -I. -MFoo=$env -le 'print scalar keys %$env'
0
$ perl -I. -MFoo=\$env -le 'print scalar keys %$env'
76

    Thanks hippo. That Package thing was a dumb typo, good catch. I'm so used to importing arrays and hashes, without having to escape the sigil, that I forgot about the pesky $hell. Thank you!
