Is there something wrong with Blitzmax that you're waiting for a fix for?
There's always room for improvement...
I've generally found BRL very receptive of ideas and code-tweaks to BlitzMax.
I suppose the reason I come upon situations where a code-tweak is necessary (like recently for BRL.Audio), is that I tend to push BlitzMax in directions that perhaps Mark & co didn't originally see it heading. It is after all a games programming language, apparently, which sits nice for those that use it in its raw form. For everyone else, we can just keep pushing for improvements. They'll come :-)
