Any feedback on this? Le 06/10/2015 02:52, Vicente J. Botet Escriba a écrit :

Hi,

I would like to know what other think about the order of the pipe (See this issue https://github.com/pfultz2/Fit/issues/5).

What would be the expected meaning of

auto r1 =1 | pipable(f)(2);

f(1,2) or f(2,1)?

What would be the expected meaning of

auto f2 = partial(f)(2);

auto r1 =1 | pipable(f2);

f(1,2) or f(2,1)?

As the operator| has left-to-right associativity, we can not do

auto x = 1 | 2 | pipable(f);

We would need a way to pack the parameters

auto x = forward_as_tuple(1, 2) | pipable(f);

but this wouldn't compile as f has two parameters.

or use parenthesis

auto x = 1 | (2 | pipable(f));

and the result will be f(2, 1).

Any ideas?

Best, Vicente
