Comment (by iwakeh):

 While replying to #21934, I had another idea for this ticket:

 We could use a grammar and from that generate a descriptor parser and all
 related code.
 I'm thinking of something like
 [https://github.com/antlr/antlr4/blob/4.7/doc/index.md antlr].

 This might be an interesting project for GSOC 2018.
