...another keyword ("raii"? Unlikely to break old code, I'd venture) for RAII allocations.

That...

...very stringent restrictions on how RAII (or these "implicit RAII") class references could be used.

...and is very explicit.  'local' can be replaced with 'raii' , 'stack' or whatever you like.

void func() {
  auto int x; // x...

True.. however not being a C++ programmer "on a daily basis" I can't say...

Ah.  Thanks for the info.

Good point. That's a big problem.

I'm arguing semantics perhaps but all I did was say that it 'implied' heap...
