Description

I have a use-case where I iterate over collections in a generic manner (using templates). However, iteration over basic_json fails due to the statement:

        JSON_ASSERT(m_object != nullptr);

Before asserting for non-null object, shouldn't we first check of other.m_object is null too? If both are null, the operator should return true before the assertion.

Reproduction steps

nlohmann::json::iterator{} == nlohmann::json::iterator{}

Expected vs. actual results

Expected: Should return true of m_object is nullptr for both objects

Actual: Assertion fails
