DOC: Warn the user when they pass `default` to a TraitType. Most TraitType subclasses accept a `default_value` parameter. On more occasions than I care to admit, I've written something like: ``` class Foo(HasTraits): foo_int = Integer(default=5) ``` when what I actually meant was ``` class Foo(HasTraits): foo_int = Integer(default_value=5) ``` I suspect I'm not the only one who's had to track down this same bug multiple times.
