Sounds like a compelling case for building the <select> in the
template. Either that or you need to go to some kind of gettext-style
i18n database. You might need that anyway, for error messages and
other generated text.

That works. Something like:
<option value="foo" <tmpl_if foo_selected>selected</tmpl_if>>Foo</option>
<option value="bar" <tmpl_if bar_selected>selected</tmpl_if>>Bar</option>
Then you just set one "${name}_selected" to 1.

If you can avoid using HTML::Template::Expr then you should. It's
much slower than HTML::Template and uses more memory. But if you have
to use it anyway then it won't matter much which path you choose.
If you're worried, try both and let Benchmark.pm decide!
