[Wrapl-discussion] expr1 \ expr2

[Roman M. <rom...@gm...>]

Hi Raja,

I noticed one small inconsistency with "expr1 \ expr2"

Tutorial Chapter 3 (http://wrapl.sourceforge.net/ref/tutorial/chapter3.html)

"expr1 \ expr2 produces the values produced by expr1 for each value produced
by expr2"

ALL 1:to(3) \ 10:to(12);
actualy returns
[1, 1, 1, 2, 2, 2, 3, 3, 3]
not
[1, 2, 3, 1, 2, 3, 1, 2, 3]
as the example shows

Tutorial states that "expr1 \ expr2" is similar to "expr1 & expr2", such
that it returns the value of left for each right, in contrast to the value
of right for each left. But that (factual) way their (& and \) results are
not symmetrical.

--
the values of (left for each right) [1, 1, 1, 2, 2, 2, 3, 3, 3]
vs.
(the values of left) for each right [1, 2, 3, 1, 2, 3, 1, 2, 3]

I guess it would make sense for it to behave that way: [1, 2, 3, 1, 2, 3, 1,
2, 3]
