No. Only the commands named `in-frame' will actually evaluate in the
specific frame. Everything else, including REPL input, will just be
EVAL'd in the null lexical environment from deep in the debugger loop.

I have a feeling that people are expecting different behaviour, but
I'm not sure exactly what. Please feel free to spell it out.

It does the right thing in the examples I've tried. More details?

I'm not familiar with that, what's it do?

This ugly message really means that the RESTART-FRAME feature is not
implemented for CMUCL. I would like to improve such messages but it's
at least slightly tricky, as I believe is supporting that feature.
