Type hints that only ensure that something is a scalar are a non-starter for
me. I'm not going to waste my time on something like that. You're not going to
get any better core support with this, and you'll alienate support from a
majority of userland as well. The average function doesn't need "just a scalar,
but any scalar will do". Most functions need something specific, like a string,
or a number. sqrt('foo') doesn't make any sense, it needs a number, not just a
scalar.
