Given kscript will work as well as Ian suggests, it will be fast enough. If 
there is a interpreter loaded, and the kscript engine calls dcop methods 
directly, it should be fine speedwise.

My own main concern is the way the script API will look to the user, calling 
methods using the confusing dcop interfaces is not acceptable. We need to be 
able to do something like
  [kate.]activeDocument.insert("string", line, col)
etc. But we should be able to do that, either by the means of a local kscript 
plugin, or by adding options to the global one allowing to tweak the 
interfaces in such a manner.

The main advantage is that using kscript, we will leave the choice of language 
to the user, to the extend kscript can interface the desired language. As I 
allready said, python is working, ruby is close and others will follow. I 
suggested lua as a candidate to Ian as well, and I of course believe that 
perl is a must ;)
