Not sure rustc can do a lot about this case but maybe a static analysis tool can complement it.

  To some extent, all compilers are static analysis tools. I think clippy could be enhanced to spot this.

    Yep, it likely could. Spotting something that usually is an error now being wrapped in `Pin<Box<...>>` would hopefully be not too hard.

  If it can detect the recursion in the non-dyn return case, it seems like it ought to be able to do the same once dyn is added.
