Okay by me.

"accumulate" is a poor name for sure; I'll go add "fold" to my vocabulary :)

It seems that by dropping the prefixes it will become very hard to read PP
metacode, because there is no cue regarding the data structure. We only get
away with short, nondescriptive names in other languages because the type
system gives us some clue.
