Which is exactly the point! They were turned into keywords because the
developers didn't want to allow them being overridden. There is no
a priori reason why we should turn "True" into a keyword and allow
"int" in the builtins.

We are only allowed to be adults, for as far as the developers let us.
They allow us to be adults with regards to "int" but they don't allow
us to be adults with regards to "True".

Defending "int" being overridable by declating "We're all adults" is
being selective.
