Or the alternative approach of upsetting them all equally ;-(

No doubt the differing views have to do with the coding styles being
used. Seems like in Nice by default I use single assignment "let"
throughout the code and then change to an explicit type or var if
needed. 

These imperative usages read well:
   let s = shortName(c.getName);

and as I use this form a lot, giving them up doesn't seem like a great
idea. 

It is a little scary to catch myself writing things like this ;-)
   let s = shortName(c.getName);
   let s' = s + ...

(maybe I should give-up and use a real fp language)
