Two things, I do not like these one line expressions splitted in more than one. Maybe I can say that I do not like one line expressions at all, 'cause it costumes to be very insecure (if just only one call of the entire expression returns ```nil```, the entire expression will break and will throw an exception that the user cannot recognize and treat). 

I usually split them in more attributions. But, if you prefer keep in one line, in this case, I don't see much big problems. Just, please, indent this second line twice, for those who look at this code, understand that is a one line argument splitted in two.
