Ahh, this is pretty cool. I like the idea that System::Sub represents, but alas, it requires that I know where the executable (or script!) will be at compile time (at least, relative to the cwd).

As an aside, I can't understand how import doesn't get itself in an infinite loop! Where's the exit?!

 

But thanks; I'll definitely keep this class in mind for later projects

    "As an aside, I can't understand how import doesn't get itself in an infinite loop!"

    System::Sub::Env::import is going to System::Sub::import. Different package; different sub.

    The reason for the goto is to hide System::Sub::Env::import from the call stack - System::Sub's import method looks at caller.

    package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
