Re: ob-scheme doesn't support :stdin?

I have been thinking for a while that it would be great to have some kind of test system for Babel language implementations.  It seems there are lots of possible Babel features, that some languages support and others don't, and it would be good to have more clarity about that situation.

Is there already any testing or support matrix along these lines?

Best wishes,

Since everything that is prepended with a shebang: #! interpreter
is at the same time a valid shell script, isn't it?
