Our compiler stack is in Haskell so we initially started with Parsec (parsec combinator library) and then eventually switched to Happy (parser generator that Haskell uses itself) since we didn't have a formal grammar defined. so that made us write a lot of code for every little addition to the language (it's a simple declarative DSL, https://github.com/wasp-lang/wasp).
The problem we're now facing with Happy is that it doesn't really have support for error recovery. We're trying to implement LSP so recovery is important in order to have proper syntax highlighting and error reporting in an IDE.
Wondering how well ANTLR covers this, I was quite surprised to find out that Happy has so little support for it.
Integer arithmetic traps on overflow -- and that includes the often forgotten "divide by INT_MIN" case:

You have to use a different set of operators to get modular arithmetic semantics. So, the choice is not a flag you flip at build time, but a choice of operators.
