Good God, you mean there's a language just for the attic? Those Greeks 
certainly believed in linguistic specialization, didn't they?

Well, I suspect that Church originally chose lambda precisely because of 
its meaninglessness, and I'm always amused when mathematical types try 
to attribute an intuitive meaning to the word. It's purely a learned 
association, which some arrogantly assume simply *everyone* knows or 
should know.

Not that I'm trying to write off lambda supporters as arrogant (though I 
*do* have a suspicion that many of them break the wrong end of their 
boiled eggs).

Whereas I find it to be an excrescence, proving (I suppose) that one 
man's meat is another person's poison, or something.
