are those for type-params in a TypeBuilder or MethodBuilder. Still, more details on this
appear in Sec. 4.5 "Faulty metadata in XMLReaderFactory" of
http://lamp.epfl.ch/~magarcia/ScalaCompilerCornerReloaded/Libs4Lib.pdf
To avoid name clashes when choosing a param name,
first collect all existing tparam-names from a type (and its nested types).
