This is not the delegate literal type deduction problem.
It is a trivial mismatching of delegate types.

This is the reduced code to explain the problem.
----
struct Variant {}
class Dynamic {}
alias Variant delegate(Dynamic self, Variant[] args...) DynMethod;
void main()
{
    DynMethod dg = delegate Variant(Dynamic, Variant[]) {
        return Variant();
    };
}

Output:
----
test.d(6): Error: cannot implicitly convert expression (__dgliteral1) of type
Variant delegate(Dynamic _param_0, Variant[] _param_1) pure nthrow @safe to
Variant delegate(Dynamic self, Variant[] args...)

DynMethod has typesafe variadic parameter, but literal doesn't have.
So this is a bug of TDPL sample code, not compiler's.
