           Summary: @nogc std.range.dropOne
           Product: D
           Version: D2
          Hardware: All
                OS: All

This is borderline between bug report and enhancement request.
Perhaps this should compile:


void main() @nogc {
    import std.range: dropOne;
    auto a1 = [1, 2];
    auto a2 = a1.dropOne;
    auto s1 = "hello";
    auto s2 = s1.dropOne;
}


DMD 2.066alpha gives:

test.d(4,17): Error: @nogc function 'D main' cannot call non- at nogc function
'std.range.dropOne!(int[]).dropOne'
test.d(6,17): Error: @nogc function 'D main' cannot call non- at nogc function
'std.range.dropOne!string.dropOne'
