[Jprogramming] Deal

[Dan Bron]

Depends on which argument is "data" (calculated, changes frequently) and which is control (fixed, or changes infrequently wrt the data).  

In other words, if you wanted to make a reusable verb, which is more likely in your context:

     deal =:  3&?

or

     deal =:  ?&10

?

If the former (which is more common), I'd be inclined to write 3?10 10 10.  If the latter, I'd be inclined to write 10 ?~ 3 3 3.

My inclinations stem from the facts that it is easier for me to scan code if I know I can expect controls on the left and data on the right, and it's easier for me to write code if I can incrementally build up data right-to-left, rather than using nested parens.

But I also have to be wary of the hobgoblins of consistency.

And 3?3#10 is shorter than both, though is closer to 3?10 10 10 than 3 3 3?10.
