Nipping this historical artifact in the bud before it roots. It's often
useful to be able to `map` directly to the result of a StateT computation
and due to how Functor works this is made harder when the tuple is
(a,state) vs (state,a)
I'm playing with some linear structures and finding these useful a lot,
so good to have a consistent syntax for it. '#' is chosen because it's
short, looks a bit like a cross if you look at it from the right angle
(!) and so as not to clash with '@@' in preorder reasoning syntax.
Can't export a type which refers to a private name. This has caught a
couple of visibility errors in the libraries, code and tests, so they've
been updated too.
Now all common console IO functions available from the
prelude are available through the `Control.App.Console`
interface.
Added:
- putChar
- getChar
- getCharLn
- print
- printLn
Renamed:
- getStr to getLine
