Comment (by goldfire):
Note that they are in the `Q` monad: there's no claim to purity here. This
means it's reasonable for the behavior to depend on extensions, etc.
I suppose this could be a specification: they return the information that
`:t` or `:k` would return. And that could also essentially be the
implementation.
