i think that your ''closed'' case is the one i use. given a finite (2)
set of results i match them all.

here you have lost me. i thought the ''closed'' case was the
''let-it-crash'' style. and that one would guard oneself against
crashes by doing:

case catch (A > B) of
true ->
	41;
false ->
	42;
_Other ->
	42
end


i understand this is not what you mean, but fail to understand what it
is you do mean. sorry.
