A little help understanding the controller

[eluser]Colin Williams[/eluser]
I guess how I see it is that on some occasions, when the existing convention of /controller/function/params does not fit your need, the only way to subvert the convention is through 1.) routing, 2.) _remap() or 3.) overloading the Input class. When routing is not enough, _remap seems just right. Seems some people jump from 1 to 3.

And the key to _remap is writing it in a way that doesn't create a restrictive new convention. In other words, you don't want to have a remap function that you have to modify each time you add a function to the controller. So maybe anyone not comfortable/confident in doing that should run and hide, I guess.
