Potential loop variable fix

[gokul-the-dev]

#2918 Looks like we have a potential accidental capture of loop variable in Boxer.

The fix removes the comprehensive list iteration to conventional loop.

I'm afraid this does not resolve the issue, I believe. Take for example the following program, with code that resembles your implementation.

conds = [1, 2, 3, 4, 5]

conda_result = []
for cond in conds:
    conda_result.append(lambda sent_index, word_indices: cond)

for func in conda_result:
    print(func(None, None))

outputs:

5
5
5
5
5
