Aliases mean inconsistency. We shouldn’t unnecessarily have multiple names for
the same thing, just one. Also, for every alias we support, another reserved
word is added. Hence we only allow one set of names. This is also Facebook’s
approach with Hack, which removes the aliases entirely for type casting. I
might propose we deprecate/remove the aliases in a future RFC.

Ooh, you’ve caught me out there. The patch as it stands would permit such
non-decimal numbers, which isn’t what it should do as convert_to_long_base_safe
should actually permit only the specified base.
So, yes it does permit non-decimal numbers, but it’s a bug I need to fix.
