grammar

It would be great to see a tutorial on how to port a pyparsing based project to Lark.

The rust code in the .lalrpop files are still on rust 2015 and need to be manually updated since cargo fix won't work on those files.

We should also update the generated code to emit 2018 idiomatic code (see #2018 )

I'm trying out lexy with a re-implementation of a parser I've already got which, in part, parses register names of the form r<0..31> and f<0..15> - i.e. there are 32 general purpose registers (named r0, r1, ... r31) and 16 floating point registers.

I'd like to verify that the register number is in range when parsed, so I'd like to have something like lexy::code_point, which has tr

Tokenizer.pipe, Rules.suggest and maybe some other methods should return an iterator instead of a Vec<_> for more flexibility.
