Hello

Recently I spend half an hour looking for a bug in code like this:

eax@fujitsu:~/temp$ cat ./t.py 
#!/usr/bin/env python3

for x in range(0,5):
    if x % 2 == 0:
        next
    print(str(x))

eax@fujitsu:~/temp$ ./t.py 
0
1
2
3
4

Is it possible to make python complain in this case? Or maybe solve
such an issue somehow else?
