Thanks! Here's a reviewer patch.
For future reference, if you have a long string literal which you want to split into pieces, you can do it by just placing the strings next to each other separated by whitespace:
>>> "a" "b" == "ab" True
This is actually more efficient than writing "a" + "b"
, because it is parsed directly as "ab"
, whereas with "a" + "b"
, Python first creates two string objects "a"
and "b"
, and then concatenates them together into a new string object "ab"
, which essentially causes two useless objects to be created.
I decreased the indentation of some lines in the doctest by two spaces because later, once David Roe's work at #12415 fixes #10458, the ...
can be replaced with ....:
(two characters more) without making the indent excessively wide.

Hellooooooooo Keshav !! Could you take a look at that ? Dima though that it would be better to make both constructors available, just to check for correction :-)
