Raul,

Regarding your comment about needing paren's, I don't think I agree, unless
you are thinking because the implicit part is already a verb without
parens. Does the following experiment verify that no paren's are required.
But perhaps you mean a fork or hook needs to be used to give the verb the
extra information contained in the explicit version?

    v =. filters&(link"2) tesl"3 2
   'v' nl 3
┌─┐
│v│
└─┘
   $cntrl v image
3 2 2 3 2 2

Regarding your following observation, I don't understand your meaning. Why
do mention the explicit verb? Are you saying there is an inherent
difference between the powers of implicit and 4 : 'xxx' verbs that I don't
understand? That is, are you saying that explicit verbs can split rank that
implicit verbs cannot? You're correct that I have been able to make the
implicit verb to work well with rank 3 "filter" value. So, the explicit
form makes "filter" the left-hand (u) value of the adverb "tesl", where the
implicit form can ONLY  make "cntrl" the left-hand of the whole verb (which
I named "v" in my example above). So, maybe that is the difference between
the explicit and the implicit: the x in the explicit can force the "cntrl"
to be the adverb's argument, not the verb's argument?

"But another issue is that the left argument to your explicit verb is rank 4
and you want to split it at rank 3 with a different x& binding for each of
these items."

What do you think?
Thanks, to all,
