Do we have to do all of this to silence one warning?

Splitting simple Perl scripts into multiple files creates significant barriers to development. Folks have had a lot of trouble refactoring Perl code because of webkitdirs.pm already. Factoring out well isolated and abstracted pieces of functionality is one thing, but pulling a function that's intrinsically inseparable from the main script seems wrong to me.

This already got r+ from the bug linked to in see also.

The other option is to make the perl script a module too, but I don't know perl enough to understand how to import such a module.
eg. how to do the logical equivalent of pseudo-code:

   use filter-build-webkit qw(shouldIgnoreLine $platform);

It's not so much a warning as quite bogus way of running the script via eval and not having half the variables defined.

https://www.perlmonks.org/?node_id=621378 addreresses some part of "executable as a module"

[Kimmo Kinnunen]

In essence I agree, but also running code in a bogus way is not very good too.

Investigate how to export stuff from perl script as a module?
Move all code to the module?
Write all code in python and be done with it?

I'm not enough of a Perl expert to understand every technical detail here. But this is structured elegantly, and clearly is a good improvement.
