Callable fails to build - Callable trait not implemented

[cleversoap]

The call to load_args_and_call at line 20 of functions_write.rs causes the cargo build to fail.

functions_write.rs:20:5: 20:33 error: the trait `functions_write::Callable<'_,<generic #81>,<generic #82>>` is not implemented for the type `T`

functions_write.rs:20     data.load_args_and_call(lua)

I looked into it, and I have no idea where this error comes from.

It appears to build on 0.12.0-nightly just fine as per the last successful Travics CI build (#158)

13.0-nightly fails - which is what both the machines I was using when I raised the issue are on; it is the latest rustup version. Somewhere in the changelogs and gh-issues lies the answer I guess.

The problem probably comes from conditional dispatch and multidispatch, but knowing that doesn't help me fix it.

[tomaka]

I think that the issue is this: rust-lang/rust#18179

Maybe we could link to this issue on the Rustc issue tracker?

This may have been fixed in rustc. However there's an ICE now, so I'm not sure.

Closing as the lib is compiling again!
