* On Windows under a MinGW bash you get a a warning for ghci:

But using ghcii.sh through stack doesn't work:

My guess is that `stack.exe` executes commands using the native Windows `CreateProcess`, which has no concept of Bash-like shell scripts (since they are a foreign thing introduced by MinGW). Perhaps try something like `stack exec sh ghcii.sh` instead? (Or `stack exec -- sh -c <command>` if you want to be agnostic to whether `<command>` is a true executable or just a script.)
