Mixing std.container.array and Appender

[axricard via Digitalmars-d-learn]

Hello, is there some structure in standard library that acts like 
Appender but works also on std.container.array Arrays ?
I'd like to have the capacity of Arrays doubling every time new 
memory is allocated.
Appender requires the input to be a dynamic array, which is not 
the case for std.container.array Arrays.
