If I couldn't get that to work directly, I'd probably take an approach 
using $string.global_regexp() (poor name) to divide the original string 
into fragments where the odd fragments don't match the regexp and the 
even ones do.  Then you'd know that you need to process the odd ones to 
do the replace of { with \{.

It sucks more, is less efficient, etc. But it also works. :)
