It is problematic for readability reasons as long as you are making complex expressions:

    configuration := NewConfiguration()
    configuration[word] = parameters[values[line][column]] - parameters[values[column][line]]

vs

    conf := NewConfig()
    conf[w] = params[vals[i][j]] - params[vals[j][i]]

It takes your brain more time to parse the first line. Now, there is an obvious limit, this is probably too much

    c[w] = p[v[i][j]] - p[v[j][i]]

unless maybe the scope of the vars is very limited.
