Subject: [PATCH] allow `ElemType(XXX)` on inputs not called `T` (#414)

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