being "NaS" (Not a String)? Cause if not, I'm not sure that's a
fair comparison.
The initialization values chosen are also determined by the
underlying hardware implementation of the type. Signalling NANs
(http://en.wikipedia.org/wiki/NaN#Signaling_NaN) can be used with
floats because they are implemented by the CPU, but in the case
of integers or strings their aren't really equivalent values.

My original post was inspired by me showing my D code to

to why floats where required to be defaulted in my math lib.
His reaction what along the lines of my first post.
I think the correct mindset when working in D is to think that
"all variables should be initialized" and if you get incorrect
calculations with zero values, division by zero errors or nan
errors the most likely mistake is often that this guideline was
not followed.
