Prevent Textile from escaping pre tag

I am using acts_as_textiled to format blog entries stored in my db. I would like to include properly formated ruby code snippets in my entries using the pre tag to get the correct spacing. However, a pre tag causes textile to escape html. Is there any way to prevent this? Anyone have a trick to format ruby code without pre tags?

Thanks,

Peter
