Haven't tried your surprise yet -- but I was surprised to find that

    "\n"expr1a + expr1b    and   "\n"(expr1a+expr1b)

functioned differently -- and now I understand why.

Is multiplying a general expression by a string ("\n") actually legal 
syntax? (and if not, should my using it have triggered an error 
message?)
