Once upon a time, 

 names.push (fp.gets "\0").chop

was 

  names.push((fp.gets "\0").chop)

while 

 names.push(fp.gets "\0").chop

was

 (names.push(fp.gets "\0")).chop

But I changed this for too much ambiguity.  I miss old
behavior
sometimes, especially when I change

  p 1+2

into

 p (1+2).abs

It should be


 p ((1+2).abs)
