I'm not sure if this is all just getting overly smart about it.
There's already a loop next to this doing:

foreach my $type_lib (@{ $type_proj->{libraries} })
{
    $p->AddLibrary($type_lib);
}

I don't object to changing mine, if that's what people think who are
more familiar with Perl than I am, but I do think consistency is a
good thing. TBH, I kinda prefer the multi-line loop. I think most
people that look at these scripts are going to be primarily C coders,
so assuming each of the variations do the same job, then I'd rather
see us stick to the most C like version.

In the meantime, I'll just change it to $p->AddIncludeDir($_) for
@{$pl_proj->{includes}};. I just wanted to note my thoughts.
