Thanks in advance,
Sorry to be slow in responding, our servers were being swapped,
and I lost a bunch of email. I'm happy to share my code via email, though
it's not elegant, it's just for local use. Also, even though I've been using
lua for less than a month, my code is already "old", a new version
of lua.c has been released. The new version is even shorter than
the previous, and approaches the level of "art code", it will almost be
a shame to hack it, but that's what it's there for.
The idea of functions without parentheses, or "commands", has been
discussed in other threads, I think it's a good idea. Being able to skip
the parentheses is a convenience for commands one types dozens
of times a day. Further, they are a feature of competing languages.
We implement them line-by-line in the interpreter, the internal parser
is unaffected. Only the most common ten or twenty functions we use
get turned into commands, for example, "print". After
> command print

The basic idea is to replace spaces by commas, except in strings.
You do have to remember to say 2*x and not 2 * x, but even I can
remember that. Also
> print(x) print(y) <--> print(x) print(y)
because we don't change anything when we see an open paren after
a command word. This mod doesn't rise to the level of a language
change, but for us it's at least as useful as
> =2+2 <--> return 2+2
I don't see the = mod in the "The Complete Syntax of Lua" either!
