* A meta-function for checking a solver's support for a scalar.
* The special-case is a Meta::nil_t list, which we are going to
* interpret as the solver supporting any and all types.
* If a solver's supported_scalars type-list is nil, this
* meta-function returns true always. Otherwise, it checks whether
* the given type is in the solver's supported_scalars list.
