That is common problem also to me.
To do it like this:

    fred_result = fred()
    meaningful_name = fred_result [1]
    if meaningful_name = ... then

is better than like this:

    seq = fred()
    if seq [1] = ... then

Selecting the right names for your variables in very important for readable
code. Maybe the most important part in writing readable code and also a
difficult one sometimes.

But I find your source code of your libraries very good and clear.
