After some consideration you can now find the (dynamic) array 
implementation here[1].
With regards to (usage) errors: The data structures in libds 
allow passing an optional function `attest` via the template 
parameter `Hook` (DbI). `attest` is passed the data structure (by 
ref, for logging purposes) and a boolean value and must only 
return successfully if the value is true; if it is false, 
`attest` must throw something (e.g. an Exception), or terminate 
the process.
An example of how to use it is here[2].
If no `attest` is passed, the data structures default to throwing 
an AssertError.
