Not exactly what you're looking for, but another way to express the
above is:
def func(iterable):
for x in iterable:
break
else:
raise ValueError("can't process empty iterable")
print(x)
Otherwise, I completely agree that being unable to completely replace
the original exception is an annoyance at best.
