> We need to decide if we want to merge for 7.4.2. The arguments against
doing so are:
> * Breaks the library interface policy, e.g. because the behaviour of
`read "12e34" :: Integer` changes
> * Would mean we should bump base's version number to 4.6, which will
mean lots of packages need updating.
We could consider it a bug that `read "12e34"` worked before. If we can
reasonably claim that the other interface changes are in "internal"
modules, then we could avoid bumping the base version (I don't know
whether that's true or not though).
