On the other hand, we could use mere concatenation *instead* of doubling. 
That is, a string literal is composed of one or more string literal pieces. 
Each piece starts with " or ' and is terminated by a matching " or '. 
There's no way to have a single piece containing both " and '. To get a 
string literal containing both " and ', you simply split it into multiple 
pieces which each contain either " or ' but not both.

We are already using mere concatenation in element annotations:

  foo["bar" "baz"]
