ipdb commands obscured by variables

When i try to debug this sample script with ipdb:

n = 1
next = 1
print('end')

I can't execute line 3 because python variables obscure pdb commands:

$ ipdb test.py
> /tmp/test.py(1)<module>()
----> 1 n = 1
      2 next = 1
      3 print('end')

ipdb> next
> /tmp/test.py(2)<module>()
      1 n = 1
----> 2 next = 1
      3 print('end')

ipdb> next
> /tmp/test.py(3)<module>()
      1 n = 1
      2 next = 1
----> 3 print('end')

ipdb> next
1
ipdb> n
1
ipdb> !n
1
ipdb> !next
1

How can i proceed further with my code execution when both commands (n/next) aren't recognized anymore? (Let's assume s/step are also obscured by variables).

What i tried so far:

using ipdb3 instead of ipdb - the same problem (maybe because ipdb is link to ipdb3 in my case :))
using pdb - it works! n/next commands move to next line instead of displaying python variables. What's wrong with my ipdb?
!!n alleviates the problem - it runs ipdb version of next. If only I could alias n !!n and then repeatedly use Enter to execute it, the problem would be solved for me. But Enter just displays variable n instead of running alias n (which should resolve into !!n)

I'm using

Manjaro Linux 16.10
Python 3.5.2 :: Anaconda 4.2.0 (64-bit)
ipdb (0.10.1)
ipython (5.1.0)
ipython-genutils (0.1.0)
i don't have ~/.pdbrc file

Solution

Update in 12/14/2016:

Finally the iPython team decide to revoke this design.

The solution of your problem is use !! statement to force standard behavior.

> /home/v-zit/test.py(1)<module>()
----> 1 n = 1
      2 next = 11
      3 print('end')

ipdb> n
> /home/v-zit/test.py(2)<module>()
      1 n = 1
----> 2 next = 11
      3 print('end')

ipdb> n
1
ipdb> !!n
> /home/v-zit/test.py(3)<module>()
      1 n = 1
      2 next = 11
----> 3 print('end')

ipdb> next
11
ipdb> !!next
end
--Return--
None
> /home/v-zit/test.py(3)<module>()
      1 n = 1
      2 next = 11
----> 3 print('end')

ipdb>
