Doing something with every <class> in the raid

[Rasher]

This will be my second addon for wow and I'm currently trying to let every <class> in the raid do something.

Is there a way to do it?

for i = 1,GetNumRaidMembers() do
local class = UnitClass("raid"..i)
-- do stuff
end

would something like that work?
