Actually, what is "static" (in the D sense of predefined, knwon at
compile-time), is the *size*, and only the size. So, the proper (again using
D's sense of "static") term could be "static-size array".
Note that in english "static" and "dynamic" 's first senses are "that cannot
change" and "that can change". This is really not what those words mean in D
and similar languages. "static" and "dynamic" are used in D to mean what in
math is called "constant" (predefined) and "variable" (defined at application
time). Lol!
