Conversion between STRef RealWorld and IORef

[Wolfgang Jeltsch]

Hi,

my STRefs have the RealWorld parameter. For now, I do not unpack the
STRefs, but wrap them with the IORef constructor and use mkWeakIORef on
the resulting IORef. I guess this should be sane. Is there any reason
why this should not work?

All the best,
Wolfgang
