[Jprogramming] <"0 vs. 0(<") confusion

[Adrien Mathieu]

Hello,

I think there is a confusion. <" is not a hook, it's an adverb, because 
< is a verb and " a conjunction, and so technically <" is a partial 
application of a conjunction. More generally, if you have a conjunction 
C, uC is the adverb V such that [x] v V y is [x] u C v y and, similarly, 
Cv is the adverb V such that [x] u V y is [x] u C v y.

This is not to be confused with a hook, which is only about verbs (to 
keep it simple). You would have a hook if " was a verb.

So, to answer your question, (<") is an adverb, and 0(<")y is <"0 y 
(according to the above definition).

Looked at the Primer and LJ and they don’t really explain the jump between the “0 to the left” and the “0 to the right” transposition when a hook.  Any pointers would be appreciated.
