Within a template, a class may have a base class that depends
on the template arguments.  If you don't know what I mean by that,
you may need to do more research into C++ before writing your tool.

In programming language design, we generally use the word "sugar" to
mean some sort of language feature that isn't strictly necessary, but
which makes something easier or more convenient to express.

In C and C++, typedefs are the most obvious example of type sugar,
but things like explicit scope specifiers ("std::") and elaborated type
specifiers ("struct vector") also count.

Basically, I'm saying that, on a valid class outside of a template, you
can safely call castAs<RecordType>() on a base type.
