You are missing the point of Spark which is to provide a (super)subset of
Ada in which formal proofs about the implementation are possible.  Lack of
pointers was not a case of hubris but a deliberate and sound decision in
Spark's case.  Formal validation and verification methodologies require
unambiguous specifications and implementations.  Spark is intended to
satisfy such formal needs.

Of one should know something about a language before one chooses to
overgeneralize ;)
