Hello,

First, thank you for your work on jq!

As I couldn't find any issue matching “.[]”, I thought I'd open this: jq '.foo | .[]' works as expected, but jq '.foo.[]' barfs out a syntax error (actually, jq '.foo[]' works too). It's not a big deal given there's the alternative syntax, but it's not really intuitive (as .a.b and .a | .b are equivalent as per the docs), and at first I thought I had got the .[] wrong. :)
