H2JVM - A Haskell Library for writing JVM Bytecode

Thanks for the info. I was mostly wondering about a case such as marking something as both public and private—ideally that wouldn’t be possible, but maybe it’s last-one-wins?

Alternatively, if it were an argument to runClassBuilder then it would be syntactically impossible to supply multiple, but then it would also be a required parameter (no defaulting).

Not necessarily a big problem, it’s just the sort of thing that catches my eye with any builder pattern—how to handle restrictions based on other things done in the same “build”.
