I've found some issues meditating on the `lazy()` function. I'm reporting
them as one ticket; please tell if I should rather create one per issue.
* promise, returned by `lazy()`, has no attributes of original class:
`lazy()` thinks only about methods
* promise, returned by `lazy()`, has weird behaviour if resultclass has
`__mod__` method – it overrides it completely
* methods of promise, returned by `lazy()`, lack the `__doc__` attribute –
docstring is lost
* if resultclass explicitly define itself as a not hashable with `__hash__
= None`, promises of that class may still be hashable.
