To you, but not to Gerald or me.
To me, this is a formatting style issue that the *compiler* should keeps
its hands off of. As I said at the begining of this thread, this issue
is appropriate for separate and optional code/style checkers like
Suppose I have
for i is s:
if c(i): break
I decide *maybe* I do not want do_c in the function, so I comment out
the last line and change 'break' to 'return'. You and the OP would force
ME to also comment out or delete the 'else:' and dedent 'do_b' for no
functional reason but merely to satisy YOUR esthetic style preference.
To me, that attitude is pretty obnoxious.
