Prevent passing a universally successful parser to the many combinator #8

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Several people have reported that they wrote parsers that ran forever
entering an infinite loop. The problem is documented in FAQ [1].

Find some way to prevent passing this in runtime (by raising an
exception?), i. e. prevent passing a (standard?) universally successful
parser to the `many` combinator.
