Heh, yeah, I actually realized immediately after I sent that email
that the exact same thing could be said about +. But I don't know...
even if + might be confused with an arithmetic operator sometimes,
it's what people are used to, and I think it makes sense intuitively.
'Plus', in a very abstract sense, suggests 'put two things together',
whether with numbers or strings or anything else for which we have a
concept of 'putting together'. ~ doesn't have that advantage. If a
programmer coming from pretty much any language sees "foo"+"bar",
they're probably going to be able to guess that it's concatenations.
If they see "foo"~"bar", it is really not immediately clear what it's
