Ah; using a non-identifier for the type is actually a rather big plus. Whether coupled with reserving "byte" in itself for int(0..255) (thus annulling that particular feature) or not, I'm warming up to the idea too.
I was under the initial assumption that buffers (under whichever name) would be a rather common data type, so much that a long name for it would be silliness, in the order of the most basic and common building block of the funciton of the browser object model being 23 characters long (document.getElementById). That would hardly be the case, though.
