Well...  Judging from my experience Iterator.remove() seems to be less 
known than the other methods of that interface - although not as much as 
methods (and even the existence) of ListIterator. :-)  I would consider 
this pretty basic knowledge as you did - probably in the same area as 
the ternary operator - but empiricism often proves our assumptions 
wrong. :-)
