Default method survey results

[Gregg Wonderly]

In this day and age of the Java language, reusing existing keywords, trying to 
shoehorn them into use for a new purpose, can feel a little clumsy.  Annotations 
can provide a much better mechanism in many cases, simply because the right 
nomenclature is helpful.

However, annotations also have a very specific usage scenario with tooling and 
moment-of-use issues.  For me, this means that you can't use annotations in 
places that annotations wouldn't work with the normal annotation tooling.  You 
certainly don't want to have to have a special class of annotation that further 
confuses the use of annotations in other cases.

The use of "default" isn't awesome, but it does provide a usable demarcation 
which the compiler and run-time class loading can use to make the right decision 
for how to build the v-tables to dispatch the default method should it be 
involved some how.
