How silly I was! I don't know why I couldn't get such a approach. Thanks a lot, I forgot I could wrap a function or class...
I tested pyramid 1.3-branch and found it worked perfectly for me. But I do believe that Pyramid team have some *reasonable reason* to keep pyramid 1.3-branch alpha. Since I'm not an expert and am a beginner, I choose to accept advise from export and experienced. And I read the release notes before and found Pyramid team published the stable version of a branch in less than a month since first preview version available for download, I think I should not in hurry.
