That's good to know.  I was thinking that something like with regexpr all parameters would be marked as static and it would pick-and-choose which are actually static/constant based on the call.

Off-topic:

The game I'm working on was finally announced today http://www.leagueoflegends.com/

I'm excited because I can now talk about it :)

I play DOTA every lunch hour since a couple of months with some friends at work! I love it! I'll sure try it. :-)

That's good to hear :)

I'm surprised every day by how popular DotA is.  I'd never heard of it before I'd started at Riot 7months ago but instantly fell in love with LOL.

Apparently there where several popular songs written about DotA.

Wait, heres one I found on utube: http://www.youtube.com/watch?v=qXKd7uuehlw

Now all we need is some D songs :)

Oh and by the way another plug: Riotgames is still looking for a couple of talented experienced engineers with a good knowledge of C++/stl or Java.  I'm hoping that one day we'll get enough D engineers to write our next game in D.

You can contact me or riotgames if your interested.

Dota is really nice because it has incredibly high replayability and very good competitive gameplay. Yeah, I'm addicted too :)
I'll try LOL for sure!

Lol, a new DotA song by Basshunter, nice! :D
The previous one was: http://www.youtube.com/watch?v=0OzWIFX8M-Y , still
my favorite, although this new is still nice, it shows even some of "teh
micro".
