<shudder> Up until that example, I was actually thinking adding this to
Python would be a good idea. But that looks just plain unreadable to
me. Someone with a Perl background would also likely parse the above as
meaning:
if x and y:
print 1
else:
0
Which is actually a sensible thing to say in Perl.
Rendering the same example with parentheses:
print (1 if (x and y) else 0)
It's now less ambiguous, but looks like some sort of crazy infix Lisp. :(
Maybe it would work better with parentheses required, and a little more
verbosity? E.g.:
print (return 1 if x and y else return 0)
For chaining, the else return could be allowed to segue into a new clause:
print (return 1 if x and y else return -1 if not z else return 0)
Or more nicely formatted:
print (
return 1
if x and y
else return -1
if not z
else return 0
)
Hm. I'm still not really convinced.
