My current thought is to ascribe lhs ~ rhs the same type as lhs (thereby
making ~ consistent with ~= by making lhs ~= rhs same as lhs = lhs ~ rhs) in
case lhs is a string type. If lhs is a character type, the result type is
obviously the same as rhs.
Seems the most intuitive option to me. Also, it makes "a ~= b" equivalent to
"a = a ~ b" which is always nice.

And that kind of suggests to me that even  a = b  should work.
It has many of the same characteristics as ~=.  It's pretty
unambiguous what you'd expect to happen if not an error.

I agree. This one, however, will be very difficult to slide by Walter's watchful eye. He doesn't like hidden allocations, and a width adjustment does involve one.

P.S. I got green light from my editor's marketing folks. Will release The Thermopylae Excerpt of TDPL today for free off my website. Stay tuned. It's a rough draft but I hope you will enjoy it.
