Global::Context::StackFrame - one frame in a stack
Global::Context::StackFrame is a role.
Stack frames are only required to provide an
as_string method. The StackFrame role also provides a boolean
ephemeral attribute indicating whether a frame is ephemeral.
Most frames are not ephemeral, but those that are will be replaced when a new frame is pushed, rather than being shifted down.
