Actually, I did that before. Yet it doesn't fit well with
Strings. Example:

Str<"Hello"> is not legal. It has to be Str<cp> where cp
is a char const*.

... Also, I want to use plain literals in binary expressions.
This is OK if one, but not both, are literals:

a - 'x';  // ok
'a' | 'b'  // nope!

In many cases, like in your example, only one
is a literal.
