I don't understand what your point it.

D dynamic arrays are not simple things, they contain pointers, length, the GC
keeps the length of the allocated memory, they have a capacity and a cache.
They are managed by the GC, so they are not just are chunk of raw memory. So an
append to a D dynamic array is an abstraction, it's an high-level operation.

What I meant to say is that to program in D it's quite important to understand
this specific abstraction. So in my opinion a docs page about them can be
useful.
