Comment(by simonpj):
I have transferred your proposed design to the Wiki page [wiki:Holes].
But can you clarify? Under (2), are you saying that if I write
{{{
f x = _?foo
}}}
then you want the program to typecheck and run, even though it is
incomplete? Isn't that what `-fdefer-type-errors` is for?
About the monomorphism restriction, can you give an example?
Ideally answer the questions by amplifying the spec on [wiki:Holes], and
adding examples to illustrate.
