Thank you very much for the extensive comments.  We have
indeed not paid much attention to improving the prose yet,
focusing instead on features and semantics.  If editorial
changes are all that remain I think we're on good track for
the final draft.

I think we can accommodate most of your suggestions.

I prefer this semantics from a type-theoretic
perspective, because the type remains the
same whether the test passes or fails.  Also,
`when' and `unless' are specifically used for
side-effects, and this is consistent with other
side-effecting operations.

I would still prefer to remove "case-lambda" from the
report altogether, specifically because I think this use
case is bad style, encouraging code duplication.
