Parametrized widgets

[mfalesni]

We already have parametrized views but a parametrized Widget would also be nice.

Current code sample:

   def _remove_recipient(self, email):
        Text(self, ".//a[text()='{}']".format(email)).click()

What I would imagine:

class Foo(View):
    w = Text(ParametrizedLocator('//something[@important={name|quote}]'))

v = "instance of Foo"
# Widget recognizes that there is a parametrized locator in args and returns a proxy
v.w == "some proxy"
v.w.read() # => triggers an error because it is a proxy
v.w(name='foobar').__locator__() == '//something[@important="foobar"]'
v.w(name='foobar').read() == "something"

This would be a very similar way how we treat parametrized Views.
