Maybe there should be some function like maskUninterruptibleExceptUser
which would mask everything except UserInterrupt exception. Or maybe
UserInterrupt and some additional exception meant for use by programs,
like InterruptMaskException.

Or we could make two new type classes:

HiddenException -- for those exceptions which should not print
anything if not caught
UninterruptibleExceptException -- for those exceptions which should
not be masked with maskUninterruptibleExcept function
