I would prefer the name reserve(). It has precedent in the STL, and the
method doesn't actually always set the capacity, only if the current
capacity is less then the argument. Even then it may conceivably
allocate more than was asked for.
In other words, the name setCapacity suggests this will always succeed:
a.setCapacity(n);
assert(a.capacity == n);
...which is not the case as far as I can tell.
You are correct, setCapacity ensures that *at least* the given number of
elements will be available for appending.
I planned on making the function a property (but a bug would not allow
that), the original intended usage was:
a.capacity = 10000;
Reserve doesn't work in this context. Can you come up with a name that
does?
I'll bring up reserve (as a function) as an alternative on the phobos
mailing list, and see what people say. I kind of liked the setter/getter
idea, but you make a good point.
