    print `foo` means pretty much the same thing as system("foo"); it's just less efficient (because it reads all of foo's output into a scalar before printing it out).

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

    The back-tick (`) operator invokes the Shell and passes the content to it to be executed. See "Quote and Quote-like operators" in the online documentation ($ perldoc -f ` ).

[Marshall]: Darn! I'll look at the thread. Must not be updatinga byte count somewhere. The .exe format is a complex critter.
[stevieb]: that way, it's still "hard coded" into the exe at least, despite not being visible via Properties
[Marshall]: I also looked into PerlApp from Active State, but they don't sell their Dev Kit independent of a very expensive ($1,200) per year license anymore.
[Corion]: I would assume that the PE format hasn't changed that much since the days of yore, but it seems that I would be wrong in that assumption
[Marshall]: When I bought my copy 15+ years ago, it was just a couple hundred bucks.
[Marshall]: I looked at MS specs for PE format and I didn't see any changes in last decade, but evidenly that would be wrong.
