Extend a helper

[eluser]Filip Vanderstappen[/eluser]
I'm picking up CI again after a long time; and I'm actually building a very nice application in it.
Because I want to have very clean and reusable code I'd like to change a helper. As I don't want to do this in the framework itself I would like to extend the helper. So what is the best way to do this in CI?

And what would be the best way to extend a Library?

So, an example of what I want to be able to : I want to change the form_radio function in the form helper. And I would like by eg. an extra function form_captcha()

I wondered a little around in the code and on the forums, but I couldn't find a satisfying answer. I hope there is someone here who can sort it out.

It's a shame!

How could I've missed that! Sorry for the inconvenience… :x
