Ah, I understand--you thought I meant it to be an analogue to the n argument to explicit conjunctions.

n: is syntactically an adverb, but with the special property that x u n: C v y is x (x u y) C v y, etc. (In much the same way as [: is syntactically a verb, but has other special properties.) As you say, choice of x/y is analogous to $:

My thought was that this would take on special meaning when used in an
adverb or conjunction argument, taking effect in the context of the
either the smallest or largest such anonymous derived verb (slightly
analogous to how $: takes arguments, but in either case ignoring
containing hooks and/or forks unless they were inside some outer u or
v argument).

Here, X:, Y: would tacitly refer to arguments of the resulting derived verb.

But, it sounds like you had something different in mind...

The 'n' is for 'now', but it was a placeholder name anyway.  Why 'Y:'?
