Oh crap I had std.array.Array in mind which does have `length`

Wow, this thing is real garbage!
OK, looks like Appender is written to be fully GC-compatible and
usable with immutable data which kind of explain such
implementation. But that makes it inherently slow compared to
plain `Array` which owns its memory and gets it via malloc.
