I mean fixed (like an old school array) instead of dynamic like a
linked list, heap, skip list, etc, etc.. or whatever on earth
std::vector is equivalent to.  See my post on comp.lang.c++, actually
don't bother.

Thanks your answer was succinct, although neither..

const size_t mysize = 10000;
typedef std::vector<f> fvec(mysize);

typedef std::vector<f> fvec;

class g
fvec f(mysize);

would compile for me.

Apologies for the off topic c++.
