:)
as cover letter says hash type was moved from this set to
later series, so it's implemented.
array and radix-tree are implemented as well, but not ready for
review yet. I have strong use cases for them.
Even two of the simplest examples for tracing (ex2 and ex3)
will benefit from 'array' type.
For bloomfiler type Chema had a strong use case as well.
I was assuming he will implement it sooner or later ;)
But, surely, I can drop future features from the manpage.
