Thanks for posting that. I've wondered several times how to do an
"increment argument until condition" using the power conjunction and your
example clarified it for me.
I think it's the parentheses making the difference here:
*(u^:(v))^:_ y*
versus
*(u)^:(v)^:_ y*

A neat trick for simulating "break." tacitly with power is to modify the
shape of input on success/break condition. I.@(boolexp) returns 0 if
true, or null if not, and appending the result of I@:f, to next y can
signal break with a cheap test.
