fixture does not work with lambdas #278
Description
First of all I want to say thanks for a great plugin! I've been making extensive use of it recently. I've found a few minor issues that I wanted to raise, so I wanted to say thank you first!
The problem that I'm running into is that pytest_cases.fixture does not support lambdas, but pytest.fixture does.
import pytest
import pytest_cases
globals()['fix'] = pytest.fixture(lambda: 42) # Works
globals()['fix2'] = pytest_cases.fixture(lambda: 42) # Doesn't work
For context, I am basically doing what is described in this comment to dynamically generate fixtures, which is why using a lambda would be nice.
