Don't change anything on the terminal, shell or the Lua 
executable. That's solving the wrong thing.

Don't try to replicate the interactive BASIC user model of the old 
days. It's better to stick to something nearer to what you would 
do with compilers.

If any script takes more than 30 seconds to type, type it out in a 
nice editor, then run the file. Want to tweak the program? Edit 
the file and run it. I often keep a test.lua somewhere. Want to 
keep the file? You can give it a name based on the exercises you 
are doing.

Never type long things out twice. Lazy programmers (that's a good 
thing) find ways to save time and energy.

If you prefer a powerful editor, get ZeroBrane Studio or something 
like that. If not Notepad++ or its relatives are good.
