 suggest to me that we may need to start pushing people *away* from the
 ast module and add a lib2to3 inspired API specifically for lossless
 transformations based on the *actual* grammar of the running Python
 version

Ooh that looks promising. I might try to knock up a recipe for some
sort of "interactive Python in decimal mode", which would cover one of
the important cases for which people ask for decimal literals. It'd
not be perfect without some monkey-patch for int/int -> float, unless
simply
every non-complex number becomes a Decimal.

Or if I don't get around to it, maybe someone else can?
