I agree completely; it ought to be one or the other.  In the code I
emailed, you actually had to do a conversion step from $-strings to
%-strings to use the build-in string-mod operator.  In practice, if
$-strings were to be added to the language, I suspect some new prefix
would have to designate a new type of string object, e.g. $''
strings.  Or perhaps a different binary operator could be used.
