[Jprogramming] tacit programming

[Roger Hui]

Tacit programming with various limitations can be done in APL.

In all APLs, you can do +/

In many APLs, you can do function assignment, so you can
do sum{is}+/ .  (You can not do this in APL2.)

In some APLs (e.g. Dyalog APL), there are composition operators, 
so you can do ssq{is} +/{compose}(power {compose} 2)

For more comprehensive tacit programming, you need fork,
and only J has fork.  (In Dyalog APL, you can define an 
operator that does fork, but the definition is not obvious
and in usage is not as pretty.)
