Folks, I have an example of the do-syntax that I would like to desugar. It is an example from Chapter 28 in RWH. I think I understand the ideas behind the following STM example, but I would like to present it to others in a desugared way: tryBogusSale = do players@(alice:bob:_) <- atomically populateWorld atomically $ alwaysSucceeds =<< consistentBalance players bogusSale Wand 5 alice bob I'm having problems especially with the 2nd line in the do block (i.e. the predicate for alwaysSucceeds). I would like to try and express this in terms of only bind (->) and return. thanks!
