It was added by John Reiser (see commit 
d23159a69c818274486f1287ba6267b96f3febb7).

I just moved the main body into a function, so it's easily eval'able - 
in order to avoid {var}>& construct. As a side effect, it's 
(subjectively) a bit easier to read.

 From what I can see, the outermost parentheses along with related 
_merge fd could probably be removed. Not tested that though, no big 
difference either.
