In Ada standard library you have safe fixed-size stack-allocated associative
arrays. In D you can't even allocate safely a dynamically-sized 1D array on the
stack, and forget about doing it for 2D. Enough said.
I used to use alloca() here and there, but eventually removed it all. The
trouble is, there are three array sizes:
a) 0
b) 1
c) arbitrarily large
Dynamic stack allocation works for none of them. What does work is a fixed size
stack allocation with failover to using malloc/free, which is what Phobos'
scopebuffer does. It's analogous to the "small string optimization".
I don't agree with your assessment at all.
