PEP 350: Codetags

[Paul Rubin]

I'm opposed to pretty much every proposal of this sort.  If you want
to propose adding a feature to the language, add it in a way that the
compiler can know about it and notice when it's not used correctly.
Mere conventions that are not checked by the compiler are just more
stuff for people to remember.  That doesn't say they're always useless
but in general they should not be the subject of PEP's.
