Repeated :info giving different results

[Simon Peyton-Jones]

The trouble is that instance declarations could be in *any* module. So
at the moment GHC just reports the instances it knows about.

As time goes on, it knows about more modules, so it may report more
instances.

I agree that it's odd that simply reporting one lot makes it know about
more!
And I don't claim that this is desirable behaviour.  It'd be better if
you saw all the instance declarations that can be written in the current
scope using unqualified names.  I'll file this as a bug.

Yell if it's hurting you; otherwise it'll be low priority.

Simon
