Amaury Forgeot d'Arc <[email protected]> added the comment:
It's not fixed. range() now uses the tp_index slot, in weakrefs this becomes:
WRAP_UNARY(proxy_index, PyNumber_Index)
and indeed PyNumber_Index does not accept strings.
But try with time.sleep() instead; here the line
WRAP_UNARY(proxy_float, PyNumber_Float)
is involved:
import _weakref, time
class U(str): pass
u = U("1")
try:
time.sleep(u)
except TypeError:
print("raised, good")
else:
print("didn't raise, bad")
try:
time.sleep(_weakref.proxy(u))
except TypeError:
print("raised, good")
else:
print("didn't raise, bad")
