26287	SimpleLazyObject doesn't implement __radd__	Keryn Knight	Theofilos Alexiou	"Technically, there's a whole bunch of magic methods it doesn't implement, compared to a ''complete'' proxy implementation, like that of `wrapt.ObjectProxy`, but `__radd__` being missing is the one that's biting me at the moment.

As far as I can tell, the implementation can't just be
{{{
__radd__ = new_method_proxy(operator.radd)
}}}
because that doesn't exist, which is rubbish.
{{{
__radd__ = new_method_proxy(operator.attrgetter(""__radd__""))
}}}
also won't work because types may not have that attr, and attrgetter doesn't supress the exception (correctly)

The minimal implementation I've found that works for me is:
{{{

    def __radd__(self, other):
        if self._wrapped is empty:
            self._setup()
        return other + self._wrapped
