It should make it into 0.14, but if the 'next version' you're thinking
of is 0.13.1, I don't think it will be backported - it is a new
feature, after all.

Yep, AST transformations are only possible if the syntax is already
valid Python, so the revised input transformation system will
definitely support string transformations. But where it's possible, an
AST transformation should be easier to write and more reliable.
