Yes, this may introduce Perl's style irreversibly, we need to be 
cautious about this.

I'm thinking, if people ask these questions in their mind when reading a 
piece of Python code:
1, "Is this Python code?"
2, "What's the purpose of this code?"
3, "How can I modify it if I want to ... ?"
Maybe Python is on a doubtful way.

There is an interesting question: Will literal p"" ruin Python's (or 
other dynamic languages like Ruby) style? Why will this happen?

IMO this is an advantage, it's hard to omit flags when reading/copying 
an regex pattern.
