Comment (by neteler):

 Replying to [comment:17 glynn]:
 > Looking through pplexer.py shows that it specifically tries to handle
 literals with an "L" or "l" suffix, but there's nothing there for an
 "F64x" suffix.

 We were wondering here about the L suffix(es) but didn't realize that a
 "F64x" suffix could be an issue.

 Apparently not, here the diffences (full outputs attached to the ticket):
