#19444: sage.misc.functional.log(float(3)) raises an AttributeError

`import_statements` suggest to import `log` this way:
{{{
sage: import_statements('log')
# **Warning**: distinct objects with name 'log' in:
# - sage.functions.log
# - math
# - sage.functions
# - sage.misc.functional
from sage.misc.functional import log
}}}
While those works:
{{{
sage: math.log(float(3))
1.0986122886681098
sage: sage.functions.log.log(float(3))
1.0986122886681098
}}}
This one raises an `AttributeError`:
{{{
sage: sage.misc.functional.log(float(3))
Traceback (most recent call last):
...
AttributeError: 'sage.rings.real_double.RealDoubleElement' object has no
attribute '_log_base'
}}}
A subquestion is why do we have two implementations of `log`?
