The problem with function names as "labelToRenderable"
is that they have type information as part of the name.
Consistency of that information cannot be enforced by the language,
which makes it dangerous.
If you want type information
(e.g. to resolve overloading, for the compiler - and for the reader!)
use the language, and write a type annotation.
