As you see I went ahead and made a patch to replace ptry
, pbracket
and pfinally
by functions from Control.Exception.Control from monad-control
.
I also wanted to remove ptimeout
but it turns out monad-control
is not powerful enough to lift that type of control operation. So I'm planning to add a dedicated timeout
function to monad-control
.
This is very interesting. I need some time to understand these changes before I commit them.
Hi Jeff,
This patch adds an instance for MonadControlIO for
ProcessM
This enables users to lift 'control' operators into a process. Control operators are things like:
alloca
,mask
,catch
,forkIO
, etc.When you have this ability you can probably remove all your custom control operators:
ptry
,ptimeout
,pbracket
andpfinally
. They can be replaced by simple one-liners in terms of functions frommonad-control
. (I may even make an additional patch for this if you want)Regards,
Bas
