Currying in general is always handy to have. The possibility to say
alias map!fun funMapper;
would be cool also. If possible, having this in Phobos would be quite nice.
Bu then, I'm one of those persons that'd like to have
alias take(3) takeThree; // will then work on any range.
Instead of take(range, 3). If find the former to be much more generic.
I liked it so much I defined a small template to invert and curry these
(R,n) functions.
