Not sure if I am understanding this correctly. By bootstrapping, do you mean C does only the most basic syntax parsing, and then a fexl script (written in a basic fexl subset) does the more complete parsing?

All this stuff is really neat. Your C code interface looks quite nice and clean. I hope you release some source code soon.

And thanks for taking the time to write all this. Even though a lot of it is over my head, it's quite interesting. I'm really looking forward to playing around with it a bit and learning.

By the way, the initial release of Fexl will take a very simple form: A Universal Filter. The "fexl" executable will be nothing more than a program which maps standard input to standard output. So it's a filter. But it's universal because it is Turing-equivalent, capable of performing any conceivable function from stdin to stdout.

When Fexl runs, the first thing it does is read a Fexl function from standard input. The Fexl process then "becomes" that function, processing the tail of the input accordingly. Simple!

That was the general idea. But it's taken quite an interesting turn lately! Turns out I can parse Fexl one character at a time and build the closed executable form in a single pass as I go along -- thanks to a concept which I discovered several months ago but shelved as a mere curiosity at the time. But I'm sure using it now!

I started a proper blog here: http://fexl.com/blog , but we can still use ycombinator.com for discussion.
