I think D should really have a friendlier interface to stack-based data
structures than just alloca() (unless it already does and I don't know
about it).
Some features which I think would be helpful:
- An "automatic" array-like structure entirely on the stack that starts
out with a capacity given by the user), and which switches to the heap
if it gets too big.
- A function that can just allocate a structure easily on the stack,
taking care of constructors and whatnot... something like alloca!Foo()
to allocate Foo on the stack, and alloca!Foo(5) to allocate Foo[] with a
length of 5 on the stack (NOT Foo[5], obviously...), etc.
How does this sound?
