I’d like to make a suggestion to the GHCi developers. I believe the GHCi command to invoke shell commands (:! <command>
) is a critical part of using GHCi, and it is too much of a waste of time to type that over and over.
Solution:
Replace :! <command>
with :: <command>
. This simple change will save you from having to switch shift keys and stretch that pinky to !
every time. This is much simpler to memorize and execute, is easier on the fingers, and is not already taken. It only requires a minor modification to the input reader code.
