Detailed Description

Rule class, which represents a rule in a grammar.

Rules are distinct from expressions, in that they are expected to be top-level constructs that can have actions associated with them.

)

Constructs a rule, owning a reference to an expression.

Expressions may be shared between rules.

Attempting to do so creates a new rule referencing the old.
