Perhaps you could use modifyMVar:
modifyMVar_ :: MVar a -> (a -> IO a) -> IO ()
A safe wrapper for modifying the contents of an MVar. Like withMVar,
modifyMVar will replace the original contents of the MVar if an
exception is raised during the operation.
modifyMVar :: MVar a -> (a -> IO (a, b)) -> IO b
A slight variation on modifyMVar_ that allows a value to be returned (b)
in addition to the modified value of the MVar.
I am searching for a programmer who is good at least in some of
[Haskell, ML, C++, Linux, FreeBSD, math] for work in Warsaw, Poland
