By having to specify ByRef in the caller, you can't forget that the function 
will modify your variable (forgetting that leads to hard-to-fix bugs) and it 
help readers of your code.

I added ByRef to Gambas only to help porting VB projects. In other cases, just 
don't use it, even if you find it more practical.
