I would like to propose deprecating 'Control.Exception.blocked' in
favour of 'getMaskingState'.
The term "blocked" refers to the old way of dealing with asynchronous
exceptions (block/unblock). It can also be a bit confusing to which
"blocked" property it refers: blocked asynchronous exceptions, or a
Note that 'blocked' is already listed in the section "(deprecated)
Asynchronous exception control":
We could add an equivalent function with an unambiguous and more
masked :: IO Bool
masked = fmap (/= Unmasked) getMaskingState
However, I don't think it will be used enough to warrant its addition.
I believe the proposal is clear enough, so I will make a patch when
consensus is reached.
Discussion deadline: 2 weeks (19 February).
