Regardless of the overhead involved, you really shouldn't be calling
functions that start with __ or any that are in an internal package. They're
not intended to be called directly by anything outside of druntime or
Phobos, and they could change at any time. In the case of
core.internal.array, the only reason that any of it is even exposed is
because it had to be when it was changed to a template.
