=head1 NAME
Global::Context::StackFrame - one frame in a stack
=head1 VERSION
version 0.002
=head1 OVERVIEW
Global::Context::StackFrame is a role.
Stack frames are only required to provide an C<as_string> method. The
StackFrame role also provides a boolean C<ephemeral> attribute indicating
whether a frame is ephemeral.
Most frames are I<not> ephemeral, but those that are will be replaced when a
new frame is pushed, rather than being shifted down.
