Libraries of templates should provide the source code, so that the
user can use specializations for his own types.  If you really want a
`closed' template library, you'll really have to explicitly
instantiate all the symbols the user might need.

This is an explicit specialization, but not an explicit instantiation.
It shouldn't cause a non-weak symbol to be defined.  But if you omit
the angle brackets, it becomes an explicit instantiation, and then at
most one translation unit must include that piece of code.
