import std.range;

void main()
{
    foreach (x, y; lockstep(iota(0, 10), iota(0, 10)))
    {
    }
}

$ dmd test.d

C:\DMD\dmd2\windows\bin\..\..\src\phobos\std\range.d(4716): Error: delegate dg
(ref int, ref int) is not callable using argument types (int, int)
test.d(6): Error: opApply() function for Lockstep!(Result, Result) must return
an int
C:\DMD\dmd2\windows\bin\..\..\src\phobos\std\range.d(4717): Error: delegate dg
(uint, ref int, ref int) is not callable using argument types (uint, int, int)

This is introduced as a result of my refactor pull, which added 'ref' to the parameter types by mistake: https://github.com/D-Programming-Language/phobos/pull/1124

Actually scratch that, it seems to be more involved. When I simply remove 'ref' then I get errors in other places. I'll investigate more.

Ah I see what I've missed, the hasLvalueElements check. I'm making a pull shortly.
