Reported by Francois Maltey on sage-devel:
{{{
> log(x).operator() == ln # is True, yes the alias ln is better than
> the log name
> log(x).operator() == log # is False (this feature looks like the
> binomial one)
> log(x).operator() == sage.function.log.function_log # is True
}}}
We should define a `__call__()` method in the `Function_log` class from
`sage/functions/log.py`, to handle the base argument. Then `ln()` and
`log()` can be the same function and `log(x).operator() == log` will
return `True`.
