@lain_7 @cstross @karchie The dread phrase "formal grammar" starts to creep in, here, and you get magic instruction that's purely grammar ("how to express your desires in a magically rigorous way") and doesn't in any way tell you how to do anything operant.
(Anyone who remembers checking grammars with wetware can start to predict just how much you don't want these people casting spells. But, hey, economical of resources.)
Of course the folks from operant traditions won't talk to them.
