Taken from spec: dlang.org/function.html section Lazy Variadic Functions

void foo(int delegate()[] dgs ...) { }

void main()
{
    int x;
    int delegate() dg;
    foo( { return 1; }, { return 3+x; }, dg, null);
}

2.053: ok

2.054: Error: function test.foo (int delegate()[] dgs...) is not callable using
argument types (int delegate() pure nothrow,int delegate() nothrow,int
delegate(),void*)

...

2.060 has gotten even worse:

test.d(7): Error: function test.foo (int delegate()[] dgs...) is not callable
using argument types (int function() pure nothrow @safe,int delegate() nothrow
@safe,int delegate(),typeof(null))
test.d(7): Error: cannot implicitly convert expression (__lambda1) of type int
delegate() pure nothrow @safe to int
test.d(7): Error: cannot implicitly convert expression (__lambda2) of type int
delegate() nothrow @safe to int
test.d(7): Error: cannot implicitly convert expression (null) of type
typeof(null) to int
