def name
  @name
end

#type ⇒ Symbol? (readonly)

The type of this stack frame. This can be :import, :mixin, or :base.

:base indicates that this is the bottom-most frame, meaning that it represents a single line of code rather than a nested context. The stack will only ever have one base frame, and it will always be the most deeply-nested frame.

Returns:

  • (Symbol?)
