No. I simply acknowledge that we can use the term complexity in a lot of 
different contexts for a lot of different purposes and in each of these one *or 
more* metrics will be sensible. Trying to define or argue on which metric we 
want to use for complexity without context and purpose seems pointless. 

So my suggestions was to use complexity in the context of improving programmer 
(FSE) productivity. And I hinted at some possible measurements that might be 
useful for this. I however do not in any way pretend this is clear enough to 
work as a clear definition of complexity or even metrics. And - for me at least 
- is not clear to me that a single metric will be sufficient with the chosen 
context and purpose (I'm aware we're not even clear on purpose yet).

I'm not able to pick a single definition of complexity that fits my (maybe 
our?) context and purpose. I suspect that finding the right meaning and 
definition of complexity in this context is more than half the solution - as it 
is with most really interesting problems. 

If you have a suggestion I'm all ears :-)
