What's astonishing is how primitive the implementation of this
sometimes is.  We were very surprised to find that

	asm(".asciz \"foo\"");

didn't work.  It inserted

.asciz \

into the assembly output and then complained about foo!  The thing
inside parentheses was not even being parsed as a string token; it was
being copied at about as low a level as possible.
