I was wondering if we could be sure to get
dependingOn :: a -> b -> a
dependingOn = ....
in ghc 6.6? this has been discussed before, it is implemented in jhc and
I have found all sorts of use for it as it can be used to control let
floating and inlining in a nice general way and is trivial to implement.
(one for ghc was posted before based on primitives it already
implements)
we just need to decide on a module to export it.
the meaning is that
x = ... `dependingOn` y
returns x with an artificial dependency on y. so things using x cannot
be floated out above where y is defined.
