Having used parser combinators in Rust and Haskell (combine and attoparsec, respectively), I've found that even without applicatives, parser combinators are pretty handy—they're a step above regexes, but a step below a parser generator. > I'd also be curious to see how the efficiency of parser combinators is affected by the absence of laziness in Rust. I seem to recall that laziness makes the analysis more complicated than you'd expect, but I need to find a source... Same here, but I suspect that aggressive inlining might be pretty helpful.
