Fine, let me rephrase that as "The only really funky thing about nested
procedures is the problem of mixing them with function pointers."

The trampoline technique is one solution.  Fat pointers (i.e. passing
extra parameter(s)) is another.  Monomorphization is yet another.

All are fine as long as they don't "escape" and have to interface with
other compilers ;)

Yep.  It is a nice solution to the problem.

(But not something on the Top-100 list of important tcc things to work
on...)
