Hi Felipe,

I did consider that, but the problem is that if you do it that way you 
suddenly need to have a VERY smart case-walker. Seeing as something like 
that would make it hard to do case-statements that contained values from 
variables, I decided to go with a very simple mechanism instead of 
something like this.

That said - can you detail how you would have it work?

Cheers
