Julien Palard added the comment:
I think for some builtins it may be usefull to have keyword arguments, in the
case they take more than one parameter.
Typically, it's impossible to write:
self.drop_elements(partial(isinstance, type(lxml.etree.Comment)))
Because isinstance take its argument in the "other" order, we may bypass this
using keywords arguments:
self.drop_elements(partial(isinstance, type=type(lxml.etree.Comment)))
But isinstance refuses keyword arguments, so there is no way to write this
without a lambda:
self.drop_elements(lambda x: isinstance(x,
type(lxml.etree.Comment)))
With is cool and work, I agree, it's just an example to explicitly show why
keywords argument may be cool: functools.partial.
