Amidst the discussion, Alvaro suggested that we resolve the issue
by adding a distinct type for patterns as opposed to text. That'd
allow us to make "~" it's own commutator by defining both
text ~ pattern
and
pattern ~ text.
That's kind of a neat idea. There might be an efficiency benefit to
having a regex type that is precompiled by the input function.
What do we do when we get text or unknown in place of pattern? How are
we going to know if the pattern is supposed to be the left or right operand?
