Sure, works for me.

My recollection is that double-underscore and underscore-uppercase is
forbidden for use apart from the implementation / standard library,
and anything else underscore (underscore-number or
underscore-lowercase) can only be used for static symbols. But I'm
sure Simon will be along shortly to correct the record. :)
