When porting code from python2 -> python3, one of the biggest hurdles is getting all the things that used to be just str, converted to sometimes-str-sometimes-bytes. python3 -b warns about comparisons and likely-unsafe conversions. If -b is no longer alerting about these, what does that really mean? Is it just instrumenting the str and bytes __eq__ methods and str initializer? Or is it somehow more thorough than that?

Hi folks.
I've been porting things from Python2 to Python3 for a while, but I just found out today about python3's -b option, which emits a warning when comparing str to bytes (or vice versa), or when converting bytes to str using the str initializer. I noticed that it also seems to even help with dictionary keys - nice.
My question is: if -b is no longer detecting things to warn about, how much does that say about how far along your str-vs-bytes-correctness is?
Thanks.
