I don't think that the existence of bloat in *some* solutions for an
unrelated problem domain is an excuse to add bloat to Screen.  Or are
you specifically referring to bloated window managers for the tty?

Note that I don't believe replacing the existing, limited
domain-specific language (DSL) used in ^A: and .screenrc with an
embedded general-purpose language will *necessarily* add bloat.

Using a third-party language would (hopefully) reduce the amount of
code that the Screen developers need to maintain, as well as the
obvious benefit to users of having more customizability.

I'd certainly like the *core* of Screen to remain in C, or some other
language for which an efficient optimizing compiler exists.  I don't
mind if extra bits (for example, the code to turn the window data into
a string for %w) was converted to a language that's interpreted
on-the-fly.  Separation of "core" from "extra wank that users insist
on" might also reduce the burden on the Screen maintainers.
