I started to look at the Wikipedia page, but realized there was way too much for me to learn to even begin to understand what you mean.  Therefore, this reference is of no value to anyone without your background.

I must take your word for it.

Presumably, "abs" doesn't mean absolute value as it would in pretty much any other programming context.  That seems unwise at best.

I found your README.  The grammar section assumes I know what you mean by "abstraction" and "application," at the least, which I don't.  The examples section does absolutely nothing for me as I don't understand the syntax or terminology.  The result is that I can't make anything of your *bind* proposal.
