I guess this is changed due to JuliaLang/julia#31191 ?

I think that Core.Compiler.specialize_method should be a drop-in replacement for code_for_method.

Any chance of trying it in a PR? Would be great to add Julia nightly to travis testing as well.

[tpapp]

Sure, will do one in a few minutes.

I take that back: apparently the changes were more complex than this (omitting world age, other small changes to the reflection API) so I think this should be done someone who knows these better.

Ok, fixed on master.
