Bad predicate behavior? #26

Closed josephwecker closed 13 years ago

josephwecker commented 13 years ago

From the readme documentation:

&'a' 'b'      # match a "b" preceded by an "a"

I haven't tried the library yet but got stuck on that line - does citrus implement and-predicates so that they consume characters? In normal PEG that expression would always fail because they would be looking at the same spot in the stream.

You're right. This is a bad example. Fixed here.
