If we were going to add something like this (which I'm really not that
thrilled about due to their encouragement of bad practice as previously
discussed) it seems wrong to add it at the level of a specific binding
rather than as a general facility.  I think I'm not entirely sold on
this use case though, I'll follow up to a later message in this
thread...
