This is similar to/a extention of an idea juerd meditated upon (and which I completely missed the point of originally) this time last year at Non-destructive array processing.

Seems to me that some variation of this could be added to List::Util therebye hiding the obscure nature of the technique behind a standard interface and lifting it out of the realms of "clever code" to a useful, usable idiom?
