import std.algorithm;
void main() {
    int[int] hash = [1:2, 3:4];
    auto vals = hash.byValue();
    map!q{a}(vals); // error
}


The line of code with "map" causes this (DMD 2.053beta):

test.d(5): Error: template std.algorithm.map!("a").map(Range) if
(isInputRange!(Unqual!(Range))) does not match any function template
declaration
test.d(5): Error: template std.algorithm.map!("a").map(Range) if
(isInputRange!(Unqual!(Range))) cannot deduce template function from argument
types !()(int delegate(int delegate(ref int) dg))
