I completely agree. I wrote a parser for my 6502 assembler and nom together with nom-locate allowed me to write a parser that could recover from errors, parse trivia, return detailed error messages with locations and make everything easily unit testable. The main drawback was that because it's a strongly typed parser combinator you can end up with some pretty inscrutable errors when you combine the parsers incorrectly.
