If structs couldn't be allocated on the heap, you'd have to forget about struct
arrays. And this is pure bullshit. E.g. this wouldn't be allowed anymore:

S[] array;
array.length = 1;

You couldn't seriously want this to be illegal.

(This code snippet also shows that it's advantageous to force structs having a
"simple" default ctor, i.e. one that doesn't require the runtime to run code on
each element to construct it.)
