 The history of what has happened in your session is already in a file you
can open and edit to turn into a script.  The file is in the same folder as
prothon.exe and is called ".prothon_history".  Have you ever noticed that
the command history was remembered between sessions?

I have considered this before.  I've considered it in two contexts.  The
console as you suggest and as the core of an interactive IDE.

The reason I didn't do it in the console is that the idea quickly mushroomed
into a real shell.  At that point I realized there was no reason not to drop
out into the real shell.

The interactive IDE is going to happen in the future.
