register_namespace_callback

Register a function <code>callback</code> to be called after a namespace is loaded.
Calls <code>callback</code> once if the namespace has already been loaded before and
also adds an unload-hook that removes the load hook.

Frequently used helper functions and assertions used in
'mlr3' and its companion packages. Comes with helper functions for
functional programming, for printing, to work with 'data.table', as
well as some generally useful 'R6' classes. This package also
supersedes the package 'BBmisc'.
