Other preprocessor macros: Although Texinfo is not a (general-purpose)
typesetting language, I think of the use of processors for the troff
typesetting language. If I understand correctly, preprocessors like
eqn add commands to the language and are used to add extra features
(in eqn's case, typesetting of mathematics). Following that pattern
would be:

@end TeXblock

and the preprocessor would replace this with @ifinfo, @tex, @html or whatever.

I'm not sure if this approach would be generally useful for Texinfo.

m4: one problem I see with m4 is not executing macros by mistake, and
how it's quoting characters would fit into Texinfo's syntax. That
problem is for whoever tries to use it, though.
