I suspect I would not be the only one who finds it curious to have
the distinction between the use of "->" in File::Spec->catfile() and
"::" in File::Temp::tempdir (and all the other function calls
touched by this patch).
Wouldn't it be more faithful to the original to do:
require File::Spec::Functions;
push @files, ... map { File::Spec::Functions::catfile($f, $_) }
in the first hunk? It would save the time readers of "git log -p"
has to spend on wondering why "catfile" is an oddball.
Of course "man File::Spec" would educate readers where the
difference comes from, but it is not immediately obvious to me why
we want to switch in a "lazily load for speedup" that is supposed to
be optimization-only, even if the class method ends up calling the
same underlying thing.
Thanks.
