Depends. For obscure behavior features, ok, for 'language features' I'm probably still going to pass. Because in this example case that would come down do
# See stackoverflow/highlyupvoted/wtf/does/python/do/here
# This is the same as (a < b) < c.
x = a < b < c
whih is not clearer, not easier to parse and not faster to read and harder to maintain (leads to rot easily when variable names change) than the non-ambiguous other choice.
I would have skipped that second line and just left the line with the documentation link. If you are going to provide the equivalent code in a comment, you might as well just use the equivalent code.
