Occaisionally, the first two lines of The Zen of Python conflict with
one another.
An API I'm working on involves a custom namespace implementation using
dictionaries, and I want a pretty syntax for initializing the custom
namespaces. The fact that these namespaces are implemented as
dictionaries is an implementation detail, and I don't want the users to
access them directly. I find the "implicit update" syntax to be much
cleaner:
@namespace # indicates function should be executed in namespace
def initialize_namespace():
x = 5
# versus the alternative
__namespace__ = {
'x' : 5,
}
Of course, "x = 5" is a trivial example. The contents of these
namespaces will probably contain on average dozens of items; they are
analagous to a module's global dictionary. Most people probably prefer
to specify a module's globals with regular statements:
x = 5
... instead of explicit dictionary assignment:
__dict__['x'] = 5
