Apply is not required, you can use functions. I just hate reading inside out and backwards. compare: func3(func2(func1(x))) # Fine if the chain is short, but quickly gets unreadable x.apply(func1).apply(func2).apply(func3) # More verbose when working with short chains, but infinitely clearer and more readable when things start getting complicated, or for less experienced coders > Note that "len" and "dir" crash. > > Here is a perfect example: >>>> int(P(["1","2","3"])) > Traceback (most recent call last): > File "<stdin>", line 1, in <module> > TypeError: __int__ returned non-int (type ElementwiseProxy) It is alpha software :P Easily fixed though.
