Slick! ;)  Very clever, thanks!

Because potx still sees "$t($foo)" as if it's "t($foo)" and it gives  
the warning, anyway.  By using $tr($foo) it all works.

I guess it's a minor performance hit to do this, and it slightly  
obfuscates the code, so I doubt we can convince core to either  
implement or document this practice...

@Gabor: thoughts? ;)

Thanks,
