allow ElemType(XXX) on inputs not called T

Browse Source 
Currently, `ElemType` can only be called on `HashArray`, `HashList` and
`List` types when they are first assigned to a variable called `T`. The
templates have been adjusted so that different variable names may be
used. The templates can now also be applied to in-line computed types,
e.g., `ElemType(typeof(x))`.
