return list(self.get_parameter_dict().values())<EOL>
Combined path-level and operation-level parameters.

Any $refs are resolved here.

Note that this implementation differs from the spec in that we only use
the _name_ of a parameter to consider its uniqueness, not the name and location.

This is because we end up passing parameters to the handler by name anyway,
so any duplicate names, even if they had different locations, would be horribly mangled.
