I took a quick look at the namespace prefix section: That looks a bit
overkill to me. Also using . and / as function prefixes can easily get
confused with paths.

I'd suggest using just one name space prefix for everything to keep
things simple. It could be ::function, or pluginName::funciton for
instance.

If there are too many types, it makes it more confusing / cumbersome
when writing.
