this adverb returns a conjunction which is designed to turn any dyadic verb
into a conjunction purely for parsing convenience that a conjunction can
sometimes provide.
lrA =: 1 : '5!:5 < ''u'''
v2c =: 1 : ' 2 : (''m '' , u lrA , '' n'')'
2 1 (, v2c) 3 + 4
6 5 7
appendC =. , v2c
appendC
2 : 'm , n'
2 1 appendC 3 + 4
6 5 7
if you don't put parens around the adverb and its verb argument, then it treats
the full y as the n argument to the resulting conjunction which is usually not
what you want since that is what the original verb would do. But including one
of the conjunction arguments inside the parens, turns it into an adverb which
may provide useful parsing patterns.
