I'm writing an alternative VimL backend for PureScript based on the CoreFn dump produced by --dump-corefn. That is, I haven't forked the compiler codebase. There are two things with the regular purs compile command that would be nice to disable:

• CommonJS module output
• Checking/inclusion of <Module>.js files (foreign definitions)

Specifically the latter is of interest, as I don't want to write foreign definitions for Vim-specific things for the JS backend.

At a high level, this might be considered "disabling the entire JS backend", I'd say, so I'm not sure what would be a good name for a flag to disable it. Perhaps --no-codegen or --no-js-codegen. Anyway, I could have a stab at this and provide a PR if this seems reasonable.

Thanks!
