I *think* that came out of my .irbrc, but it's always missed one thing: 
a nice notation for class methods:


irb(main):014:0> IO.ri "close"
--------------------------------------------------------------- IO#close
      ios.close   => nil
------------------------------------------------------------------------
...

irb(main):015:0> IO.ri "open"
More than one method matched your request. You can refine
your search by asking for information on one of:
...


Of course you can always do this:

irb(main):016:0> ri "IO.open"
--------------------------------------------------------------- IO::open
      IO.open(fd, mode_string="r" )               => io
      IO.open(fd, mode_string="r" ) {|io| block } => obj
------------------------------------------------------------------------
