So, #PHP has fluent interfaces, but it also can do fluent functions: functions that can be chain called.

As usual, it works but it is a tad cumbersome.

@dseguy Do you have any thoughts on use-cases for this approach that a recursive function wouldn’t solve? Getting back the function itself doesn’t seem terribly useful, to me. Maybe if the input params are passed by reference?

@ramsey I don't see anything practical for this: the result extraction is way too cumbersome and un-modern.

Although, the chained calls looks quite nice, and 'fluent function' sounds also terrific.

And, of course, blame @heiglandreas (for inspiration).

@dseguy @ramsey @heiglandreas Changing f($v1, $v2, $v3) into f($v1)($v2)($v3) is really just currying.

@Girgias @dseguy @ramsey @heiglandreas This is curry.
