Support for enums?

[janneromell]

Is there support for parsing fully qualified enums for odata $filter with this pegjs code?
Seems not.
odata v4 syntax is:
$filter=enumAttribute eq ''

qualifiedEnumTypeName = namespace "." enumerationTypeName

example:
messageType eq XCommunicator.Messaging.MessageTypeEnum'Mail'

value inside SQUOTE's probably needs to support multiple values separated with COMMA as well.
