Comment (by SimonKing):
Some other little speed-up:
{{{
sage: def test1(cls,name):
....: s = "%s.%s"%(cls.__name__, name)
....:
sage: def test2(cls,name):
....: s = cls.__name__+'.'+name
....:
sage: timeit("test1(ZZ.__class__,'element_class')", number=10000)
10000 loops, best of 3: 2.15 µs per loop
sage: timeit("test2(ZZ.__class__,'element_class')", number=10000)
10000 loops, best of 3: 1.85 µs per loop
}}}
So, adding strings seems to be faster than inserting into a format string.
