E.g. url = BuildURL('example.com', trailing_slash=True) so one can set it from the beginning:)

Hello, http://www.example.com/path can be different from http://www.example.com/path/ or even might not exists at all. So it would be good to have an option to keep trailing slash.

It would be nice if methods add_path() and add_query() return self so one can easily chain calls like u.add_path('foo').add_path('bar')

Also fluent setter for trailing_slash would be helpful. E.g.:

def set_trailing_slash(self, enabled = True):
  self.trailing_slash = bool(enabled)
  return self

It would be convenient to be able to call methods like this:

url.add_path('foo', 'bar', 'xyz')
url.add_query(foo=1, bar=2)

I've only discovered furl after creating BuildURL.

They have a lot in common, so it's worth referencing furl as a possible alternative.

• Bug part: I was trying to do something like .add_path(['user', 123]) and it didn't raise an exception during the execution of the method but only when i called .get, which is imho late.

• Feature request: Everything should be converted to str automatically (not raising error) or at least usual types like int, float. I think it should be user's responsibility to provide desired str output and everyone knows that resulting url is always str.
