The problem is some engineers are ideological, you don’t want to work with those. If you have this argument during an interview and the interviewing engineer is insisted that X is always the right choice, run away.

Anytime a commercial language gets bogged down in parsing, unless that is core to the product (and mostly it isn’t), also run away. Parsing represents like 1% of the work that needs to be done on a compiler, even if it’s an IDE parser that needs to be really incremental (the only worse thing is to get stuck on lexing).
