ef prefix

I've seen some extension use the 'ef' prefix for global function names (presumably standing for 'extension function'). Is this a proper coding convention or some unholy bastardization? Is 'wf' or 'ef' preferred for global function names in extensions?

ef has been used since ancient times, but it's not super common now. In most cases modern style puts hook functions as static methods on a class, leaving few or no raw top-level functions to be so named.
