I recommend:
Foo::Bar->do_it();
Many more modern CPAN packages are written this way. Older packages
require you to do:
Foo::Bar::do_it();
It's better than just:
do_it();
However, many packages (which shall remain nameless) don't make it
easy to find Foo::Bar, because they mix everything up. To me, all
Foo::Bar functions should be defined in Foo/Bar.pm. That's the way
bOP is organized, and it makes it very easy to navigate.

I'm not sure if you mean this:
use vars qw($Getopt::Std::opt_h);

I think you can get them to generate anything in "aux" files. That's
how bib entries and such work.

Understand. I thought the dataset was constrained.

Well, not really. TeX commands are macros and easy to interpret, but
we won't got there. ;-)

That's great. I don't think there is a big market in LaTeX to HTML
translators:

And you'll solve that problem when you come to it. That's Extreme
Perl at its laziest!

Ditto.
