I question your assumption that
"Result" is specifically more important than the other incompatibilities
among different modes (i.e. your statement that it "will help...a lot"). I
do not say that it is wrong to be more helpful in error messages, but
rather that your proposal tries to "fix" a very small fragment of
something much more general and moreover that the proposed message may be
very easily misleading as already demonstrated by Mark. Yet other cases
might not be detected by the compiler at all:
+1. Since Result is not really special, i.e. it can be declared by user, it
would be difficult to detect whether it's user's intention or not.
Treating just Result as a special case might not be worth while.
However a more general feature could perhaps be useful:
as the compiler knows all the keywords of all its modes, if an
unresolved identifier happens to match a keyword of a different mode, a
warning, sort of "wrong mode?" could be added. The overhead should be
negligible, because it would occur only in case of unresolved
identifier, and after a few of them compilation is stopped in any case.
