This makes sense, so my rhetorical question was stupid.
The times when I felt the lack of general overloading was when
constructing general symbolic expressions, where it would be
_convenient_ for 'a < b' to evaluate as a symbolic expression. But
this feels like a fairly unusual use case and not worth messing with
the core.
