When an instance value is passed explicitly, we still have a place in
the code that identifies which functions need to be specialised, and
what they need to be specialised against.

If implicit resolution is guided by TLS, dictionaries must /always/ be
maintained, even if they are never used.  The alternative is
specialising all of the code for each dynamic contour.
