yes indeed, I had no idea it was structured like that.

The first steps towards implementing a namespace (like java's import  
java.swing.*, for example) are in place.  You can use objects of the  
same name with a namespace prefix, like [cyclone/prepend],  
[iemlib/prepend], [ggee/prepend], etc.  Then you could [import  
cyclone], and [prepend] would then be cyclone's prepend.  The next step  
is to make patch-level namespace, currently there is only a global  
namespace.
