[issue12142] Reference cycle when importing ctypes

[poq]

poq <poq at gmx.com> added the comment:

Tests succeed with this change.

There is only one use of _array_type, which is in the same module. This use is presumably tested, because the test fails if I change the line to _array_type = type(Structure).

In fact, everything must behave exactly the same after this change, because the two values are identical:

>>> from ctypes import *
>>> type(c_int * 3) is type(Array)
True
