Appender and Array

[bearophile]

[I don't know what's the right group to post this. Maybe the main 
D group is better.]

This is a recently closed enhancement request about adding the 
"~=" operator and more to Appender:

I have discussed about the idea of also adding a length attribute 
to an Appender. Thinking about it, isn't it possible and a good 
idea to deprecate the Phobos Appender, improve std.array.Array 
appending performance (if necessary), and add a "data" attribute 
to Array (if necessary), to replace the use cases of Appender 
with Array?
