It would be more like perl, but I didn't implement the class as 
static and I'm not sure I'd want to.  (I know I've run into 
situations in perl where I clobbered the results of a match with 
a subsequent one, unknowingly.)

No ;)  I always wondered why perl did it the way they did.  Then 
again, in Gambas you can't do an assignment and compare the 
result of the assignment in a single statement as you can in 
perl (or C, etc.) so I can see why one would want to do that in 
Gambas.

I'm not aware of any current Gambas methods that change one of 
their arguments, and I think that's contrary to Benoit's design 
intentions.  But he can correct me on that ;)

Have you tried it as it exists now, by the way?  I realized after 
posting it that those who'll want to try it are gonna have to 
manually change a few automake macros (according to the 
instructions for building your own components in the gambas 
wiki) and some people might not realize that.
