So ... not to put too fine a point on it, but ... as useful as
function notation could be for the present purposes, you seem to
agree that because of syntax limits, "where" isn't an answer to
the problem. Recalling that we were talking about a common pattern
v <- fx
case v of ...
... (where v never appears again)
Where a Haskell programmer's reflex seems to call for fx >>= case ...,
or from the old thread mentioned earlier, a lambda with multiple
definitions -
