Seed version. The seed should be a single value if fun is a
single function. If fun is multiple functions, then seed
should be a std.typecons.Tuple, with one field per function in f.
For convenience, if the seed is const, or has qualified fields, then
reduce will operate on an unqualified copy. If this happens
then the returned type will not perfectly match S.
Use fold instead of reduce to use the seed version in a UFCS chain.
