Howto not Full closure?

[Frank Benoit]

I often use local functions and lambdas. I also often pass their
address. And most of the time, i do this in environments, where i don't
want use heap allocations.

In my cases i know, that the function/method I call will not store the
delegate address for later use. It will use it immediately.

Is there a way to not heap allocate the stack frame?
Is there a language feature missing to tell this to the compiler?

For me, those local functions and lambdas are a really valueable and
perfomant language feature. With the implied heap allocation this
feature dies for me.

Not taking the address or not referencing local variable is not an
option for me.
