ipi doesn't work with multiline inputs

[disconnect3d]

TL;DR:

pwndbg> ipi

In [1]: from ctypes import *

In [2]: class A(LittleEndianStructure):
   ...:     a = LittleEndianStructure
   ...:
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

----> 1 class A(LittleEndianStructure):
      2     a = LittleEndianStructure
      3

<ipython-input-2-814bd2a1d7ec> in A()
      1 class A(LittleEndianStructure):
----> 2     a = LittleEndianStructure
      3

NameError: name 'LittleEndianStructure' is not defined

In [3]: ctypes

In [5]: def foo():
   ...:     return LittleEndianStructure
   ...:

In [6]: foo()

Whereas this works in pure GDB python interpreter:

pwndbg> pi
>>> from ctypes import *
>>> class A(LittleEndianStructure):
...   a = LittleEndianStructure
...
>>> A.a
<class '_ctypes.Structure'>
>>>
