Subject: capitalize bug?

Hi!

I'm a new member here, though I use and enjoy ruby for about three 
years. There's a beginning to everyuthing, including thing not doing the 
way you think they should, even in ruby!

So here's my problem:

@nom = wnom.gsub(/_+(.)/, '\1'.upcase)

What this code should do is taking the string wnom, and removing every _ 
and at the same time capitalizing the letter immediatly after.

for instance do_it_now would become doItNow. One way to translate ruby 
usage into camel case.

but this code does in fact producte doitnow instead of doItNow.

Now, I am not blocked, because I have achieved my goal with this code:

nom = wnom.gsub(/_+(.)/) { |deb| deb[1, 1].upcase }

but this is less clear, and surely less efficient (although this is not 
a real problem in my case).

My question is WHY does my first code NOT do what I think it should?

Thank you for your help.
