<p class=MsoNormal>I was recently bitten by the urge to hack around with STM,
and discovered to my dismay that there's no way to get at the primitive
constructors for TVar and STM, both of which are defined in GHC.Conc. Given
that, when we so desire, we can get at the primitives to break IO into pieces,
manually unbox integers and such, and that the primitives for working with
MVars are similarly exposed through appropriate imports, it would be really
nice (or, well, at least fun) to be able to do the same for STM.<br>
