[Gambas-user] To wish list; optional compiler warning

[Jussi Lahtinen]

After I read what Fabien wrote, I realised what you meant and I think you
misunderstood my problem.

My problem is *not *that I have to write byref to function declaration and
to function call.
My problem is that if I forget to write byref to function call, I will get
silent bugs.

I think either byfer should be mandatory to write to function call, or there
should be warning from missing byref keyword.
