Challenge: reimplement `foo` such that above unittest will
compile. No cheating with malloc etc. Bonus points if you
don't have to implement a modified version of std.algorithm.map
import std.algorithm, std.range;
auto foo(R)(R a, immutable int b)
{
return a.map!(x => x + b);
}
@nogc @safe unittest
{
int[3] test = [1,2,3];
assert(test[].foo(3).equal(only(4,5,6)));
}
does this count?
Oh, I think I see what you were asking. It doesn't compile with
LDC, but it compiles just fine with latest DMD.
hmm
