However, the root node of this subthread was my statement about the needless
incompatibility introduced by changing print in 3.x, whether that statement was
correct or reasonable / whatever.
The main problem with the incompatibility is for porting code, not for writing
code from scratch. It's also a problem wrt. learning the language. And I see no
good reason for it: print can't really do more, or less, or more conveniently
(rather, one has to write a bit more now for same effect).
