Is it a joke? Array expression in D are for performance reasons to
generate x2-x100 faster code without any compiler optimisations. Link to
one of these epic comments (even x100 more epic because of '%' use
instead of 'x###'):
But `a++` should store a copy of `a`, increment elements and return
stored copy. It is hidden GC allocation. We already have a silent
allocation in closures, but here a _really large_ peace of data can be
allocated. Yes, this allocation sometimes can be optimized out but not
IMHO, D should not have `a++` operator.
