I would say use ^ and v, but something tells me that disallowing a v in identifiers would be a bad idea (e.g. eval) ;)

My biggest problem with using Unicode is that it's often a pain to type. The Mac gets this the most right of any platform I know, but even so, it's (a) not a standard, and (b) mostly alphabetic. Which is a pity, really, since those do make the most sense.

According to Wikipedia (http://en.wikipedia.org/wiki/Logical_conjunction and http://en.wikipedia.org/wiki/Logical_disjunction), we could use ∧, ^, &, &&, or . for andf and ∨, v, |, ||, or + for orf. + might not be bad, but it's probably a little too common.

Agreed. We might be able to add a hook to arc-mode in emacs to make it more convenient, but reminds me even more of APL (which if I recall correctly required a custom keyboard to type).

I like +. While + does get used in symbols occasionally (most notably in arithmetic), I can't think of any cases where it gets used in the middle of a symbol.

EDIT: On second thought, when I use plus outside of a programming context, I usually mean and, so it might be confusing to use + as 'andf.

The problem with "adding a hook to arc-mode in emacs" is that then you alienate everyone not using Emacs. And that's a good point about + being used to mean &.

Or if using vi you'd add a vi macro, etc.

But point is, whatever editor you did use would need special configuration to type those characters.

· would be andf + would be orf

How do you type '·' (not '.') on a standard keyboard?

On a Mac U.S. QWERTY layout, option-shift-9. Same problem, only slightly reduced.

Using windows: hold the Alt key and then type 250 on the num pad and than release Alt. but you're right, that's not an option.
