docs: some imports are omitted

[kuraga]

Hello! Thanks for your work!

Some imports are not displayed in the docs:

import operator
from cachetools import cached, cachedmethod, LRUCache, TLRUCache, TTLCache

But they are used there.

P.S. Get rid of the one usage of the operator? It would be simpler.

@kuraga Thanks for the input! Examples generally assume from cachetools import *, I guess that's more or less in line with Python's standard docs, e.g. https://docs.python.org/3/library/functools.html
Regarding operator, that maybe should be stated explicitly. What's your issue with operator, i.e. how could this be made "simples"?

[kuraga]

@tkem ,

@cachedmethod(lambda self: self.cache)

is more understoodable (in that context) IMHO than

@cachedmethod(operator.attrgetter('cache'))

and doesn't imply (another) implicit import operator.

@kuraga You may have a point here ;-) I'll think about it, thanks!

[kuraga]

Ok, have a nice day! :)

[tkem]

Would you care to make a pull request for that?

@cachedmethod(lambda self: self.cache)

Sounds pretty reasonable ;-)

[kuraga]

'll make tomorrow both of them.

[kuraga]

Would you care to make a pull request for that?

@cachedmethod(lambda self: self.cache)

Sounds pretty reasonable ;-)

Pushed in #297.

Merged #297 into master, thanks!
