Dan Bron's posts have triggered my sluggish thinking into realizing how to make a tacit instance of R:
R3=:1 :0
u~/@|.@([EMAIL PROTECTED]@]`0:`]}~) :( u~/@|.@((u {.)`0:`]}))
)
Or, if you prefer
R4=:1 :(0 :0-.LF)
u~/@|.@([EMAIL PROTECTED]@]`0:`]}~)
:
(u~/@|.@((u {.)`0:`]}))
)
If you type that in manually, note that the : in R4 should
be indented.
