How do I skip an expression in the ghci debugger? :force doesn't seem to work...
kuribas 2017-03-05 01:09:54
I am using :step to step through the expression.

Also why can I not inspect the whole environment in the debugger?

It only allows me to inspect variables in the expression under focus.

Can anyone tell me how haskell STM or STM in general deals with Reentrancy?
hpc 2017-03-05 01:28:49
it doesn't
hpc 2017-03-05 01:28:59
look at the docs for unsafeSTMToIO
hpc 2017-03-05 01:29:17
rather, https://hackage.haskell.org/package/base-4.9.1.0/docs/GHC-Conc.html#v:unsafeIOToSTM

abhiroop: STM actions are always reentrant, as long as you don't use 'unsafeIOToSTM' &friends
abhiroop 2017-03-05 01:38:52
dramforever: "STM actions are always reentrant" -> Could you please elaborate on this?
abhiroop 2017-03-05 01:39:28
In fact 'unsafeIOToSTM' which hpc pointed seems to be the only thing handling reentrancy
