That assumes that there is a DOM tree to be parsed.
An example of a method that preserves context is the CGI module.

This defeats the entire point of a template language. If I have to call
methods to DWIM, I might as well write it all in raw Perl code.
Note, again, that Mason is a *general-purpose* template language, not
necessarily a *web* template language.

One thing I've (ab)used Mason for in the past is dynamic generation of
kickstart configs for Fedora network installs. There was a minimal amount
of Perl in an <%init> block, and the heavy lifting was handled via Mason
template inheritance. No <%perl> blocks at all, and I shudder to even
think what that would have looked like had it been a requirement.
Actually, it probably would have looked like Template Toolkit, because that
sort of onerous requirement would have made Mason the Wrong Thing for the
project. (And perhaps it was anyway, but I like to think the final product
was quite elegant.)
Don't assume that people have done it your way. TMTOWTDI, after all.
