    # Represents a StaticExpression for expressions where
    # the keyword does not vary dynamically. These static keywords are then
    # predefined as methods in Glimmer instead of needing method_missing
    #
    # StaticExpression subclasses may optionally implement `#can_interpret?`
    # (not needed if it only checks for keyword)
    #
    # StaticExpression subclasses must define `#interpret`.
    # 
    # The direct parent namespace of a StaticExpression subclass must match the DSL name (case-insensitive)
