Mixin's arguments can't work with IE filters (and other unusual places)

[devgru]

I tried to use: .ie-opacity (@opacity: 0){ filter: alpha(opacity=@opacity); }

And I always get opacity=0 ('cause it's default value), with any @opacity given.

yeah this is really annoying - filter: alpha(...) is useful sometimes

+1 for this!

cloudhead, any progress on this? this is key feature!! I won't be able to actually use less without this one.
