The +problems with it are: + +* It makes it so one can't jump into the middle of a file and know whether a bare literal string is + a byte string or text string. The programmer has to first check the top of the file to see if the + import is there. +* It removes the ability to define native strings (a string which should be a byte string on python2 + and a text string on python3) by a string literal. +* It makes for more context switching. A programmer could be reading one file which has + `unicode_literals` and know that bare string literals are text strings but then switch to another + file (perhaps tracing program execution into a third party library) and have to switch their + understanding of what bare string literals are. + |
