The problem with trampolines comes about when you want to take the

function, while you also have variables captured by reference.

Sounds like a C-issue (not one of nesting functions). Usually I use
nested functions to have and use them locally and not in surrounding
or global scope. - I'd expect a C compiler to notice such situations.

 

Nested functions were never as interesting for C++ as you already have
better mechanisms for controlling scope and data access - classes and
their methods, including nested classes.

Indeed.

(You could also omit use of C++ templates completely and emulate them
with class inheritance; nonetheless they are useful and convenient to
have them supported as concept as well. - Just for another example.)
