I am not familiar enough with the syntactic capabilities of Dyalog's
execute to say for sure.
But, 3 : can be used in place, with modifiers or any other part
of J's execution capability.
Also, I tend to think of 3 : not as an entity to itself but as
an instance of the : operator. So things that hold for 3 :
also hold for 0 :, for 1 :, for 2 :, for 4 : and maybe for 13 :
(I do tend to think of u : as something not so related,
because u : does not treat strings, nor boxed strings,
nor 0 in the same fashion as the other : forms treat
them.)
Anyways, can you use ({thorn}DFN)/1 2 3 in Dyalog,
as a simple example? (Practical examples in
J are more likely to use the rank conjunction, but I do
not want to push this into territory I know is currently
irrelevant.)
