Overview

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) (e.g. Glimmer::DSL::SWT::WidgetExpression has a DSL of :swt)
