render_each(enum, template, opts=(no_opts = true; optimized_template = _cached_render_each_template_method(template); OPTS))

For each value in enum, render the given template using the given opts. The template and options hash are passed to render. Additional options supported:

:local

The local variable to use for the current enum value inside the template. An explicit nil value does not set a local variable. If not set, uses the template name.
