How to instantiate a map with multiple functions. I looked into
the docs at
http://dlang.org/phobos/std_algorithm_iteration.html#map. They
contain a string which I suppose is a mixin and when I change "a"
to some other name it results in an error for me. Are there any
ways to use lambda functions directly instead of strings and any
explanation of the strings used in the map example and why a is
used will be helpful.
I tried reading the source
https://github.com/D-Programming-Language/phobos/blob/master/std/algorithm/iteration.d#L520 .Some hint that "a" should be used at https://github.com/D-Programming-Language/phobos/blob/master/std/functional.d#L101 but how do I change that since map doesn't allow me any params to specify the parameter name. Also how can I map an array of tuples with two or more elements with a function of two or more params like unpack the tuple into a function like that. I am D beginner so any will insights will be very helpful for me.
