Reverse a word in Vim

Question

How can I reverse a word in Vim? Preferably with a regex or normal-mode commands, but other methods are welcome too:

word => drow

<

If you have rev installed (e.g. via MSys or Cygwin) then it's really not this difficult.

Select what you want to reverse and filter (%! ) it:

:%! rev

This pipes your selection to your shell while passing it a command.
