          Issue ID: 23956
           Summary: [REG2.099.0] Can't decide between const and non-const
                    overload with lambda
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: rejects-valid
          Severity: regression
          Priority: P1
         Component: dmd

//////////////////////// test.d ////////////////////////
struct S
{
    void fun(scope void delegate(      int []))       {}
    void fun(scope void delegate(const(int)[])) const {}
}

unittest
{
    S s;
    s.fun((arr) {});
}
////////////////////////////////////////////////////////

Compiler says:

test.d(10): Error: `test.S.fun` called with argument types `(void)` matches
both:
test.d(3):     `test.S.fun(scope void delegate(int[]) _param_0)`
and:
test.d(4):     `test.S.fun(scope void delegate(const(int)[]) _param_0) const`

Looks very similar to issue 23274, may be the same underlying bug.
