lambdas are a bit older than that IIRC, and I don't think that UFCS actually 
affects the lexer or parser. Yes, changes are still made, but they're 
increasingly rare, and most of the stuff being changed is on the semantic level 
(most of which is bug fixes). So, out of all of the parts of the compiler to 
duplicate, those are the least likely to have to have major changes made to 
them later (especially the lexer).
