'As for saying that lex and yacc "implement DSLs", that is a huge simplification of what they do.'

The DSLs I'm referring to are the lex input format and the yacc input format, both of which are specific languages for the domains of lexical analysis and parser generation respectively.

Ahh... I thought you meant that lex and yacc are typically used to implement DSLs.
