Potential bug: len([<filter object at 0x1051e2bc0>]) always equals 1.

melt/melting.py

Line 127 in 3152034

fgc = len([filter(lambda x: x == 'G' or x == 'C', s)]) / float(len(s))

Is there an issue with this line? Unless I'm misunderstanding, the square brackets make a new list containing a single filter object. This will make the "GC content" 1/len(seq).
