const_cast<qx::switch_const_t<std::remove_pointer_t<decltype(this)>>*>(this)

This macro is made for situations where you have a const method and you need exactly the same method but non-const.

Warning

You can also use it in vice-versa situations, but be careful as it will break your const guarantees

int foo() const
{
    // some complicated stuff
}
int foo()
{
    QX_CONST_CAST_THIS()->foo();
}
