Comment (by simonpj):

 > this means a larger code size.

 Why??  In both cases I'd ultimately expect to see a top-level machine-code
 label for a literal string, and a reference to that label in the compiled
 code.  I see no reason for increased code size, or increased bytes-
 allocated.

 Can you explain?

 Simon
