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

<

I realize I'm a little late to the game, but I thought I'd just add what I think is the simplest method.

It's two things:

• Vim's expression register
• pyeval (py3eval on recent vim releases) function

So to reverse a word you would do the following:

• "ayiw yank word into register a
• =py3eval('"".join(reversed(str(' . @a ')))') use vim's = (expression) register to call the py3eval function which evaluates python code (duh) and returns the result, which is then fed via the expression register into our document.
