This sounds promising, so
(<(,'0');1)`+
seems like there is a need for a new primitive say `.. (tie below)
ar =: 1 : '5!:1 <''u'''
isNoun_z_ =: (0 = 4!:0 ( :: 0:))@:<
isgerund =: 0:`(0 -.@e. 3 : ('y (5!:0)';'1')"0)@.(0 < L.) :: 0:
isgerundA =: 1 : ' if. isNoun ''u'' do. isgerund m else. 0 end.'
tie =: 2 : 'if. u isgerundA do. if. v isgerundA do. m ar , v ar else. m , v ar
end. else. if. v isgerundA do. u ar , n else. u ar , v ar end. end. '
so the above could be displayed (lr) and input as
1`..+
but
(<(,'0');1)`+
wouldn't break anything since its a valid lr that creates the valid gerund. I
can't imagine anyone was relying on buggy lr output that doesn't convert back
to ar form.

Subject: Re: [Jprogramming] fixed tacit produces an error when reassigned
I understand this problem a little better now.
The trouble would be something like
v0`v1`n2`v3
where the n2 is a user-created AR. How should you convert this back to
linear rep?
There are no fingerprints to indicate that a gerund was created by (`)
turning a verb into an AR. So when the LR is generated, any AR that is
an operand to (`) is assumed to have been created by (`).
One solution would be to make an exception for noun ARs, i. e. those
beginning with (<'0'). Those could be left in boxed form, rather than
converted back to their value, when they appear as operands to (`).
Would that change break anything?
