An opportunity of using a colon is that it allows::
dotted.module.name:expression
where expression may be more than just a name::
foo.bar:Bar()
The reason setuptools uses ':' is that it allows you to unambiguously
reference object attributes, e.g.:
some.module:SomeClass.some_method_or_attribute
(It doesn't allow expressions, just dotted "paths".)
