Don't forget that you can rewrite a "for-if" using two additional
lines and no indents, rather than one line and one indent:
for ...:
if not (...):
continue
...
...
So you can take your pick which version you want. Granted, I can still
see value in the for-if statement, but not enough to justify new
syntax.
