It depends on the module, if Foo::Bar exports a procedural
interface by default then it won't shorten anything.
If it optionally exports functions then you have to
type them in the export list (-MFoo::Bar=blah,asdf)
in addition to the code.
Dev::Bollocks doesn't export anything so you'd need to
repeat the module name:
perl -MDev::Bollocks -le 'print Dev::Bollocks->rand()'
perll -le 'print Dev::Bollocks->rand()'
I often use one liners like this to test drive a module,
sometimes to filter things (eg. with Email::Valid).
I expect that the -MSome::Long::Name -e '$s=Some::Long::Name->new()' type scripts will
BTW, I've only just started using this alias so I don't
have a much of feel for it yet...
