I think it was earlier in the thread. I interposed
because a side effect of a suggestion I made some
years ago was to provide a facility equivalent to
third and fourth arguments.
My need in teaching was to be able to bring verbal
operands simply in to tacit expressions. I was
trying to teach tacit J as perhaps the purest form
of functional computing
(see www.vector.org.uk/archive/v233/tji.htm)
and I found that unhappily I had to also teach my
better students how to code explicitly when they
were doing their projects to get around problems
could be solved tacitly if something like the [.
and ]. I suggested on this forum were available.
The simplest cases (as far as I can remember from
about a decade ago) were to bring an operand in to
various places in a train. Easy explicitly, very
difficult as tacit is, easy with the [. and ]. of
my suggestion - to explain/teach as well as to do.
