Are you sure about this? Perhaps you should
provide a small program that triggers this error.

Vala references are like C pointers -- raw,
unwrapped, direct and optimizer friendly (though
I notice that the vala compiler puts an
additional indirection for private variables,
incurring performance penalty in object construction
and subsequent accesses).
C++ shared_ptr is an ugly wart. Its only similarity
with Vala references is ref counting.
Do not let your experience with shared_ptr
discourage you from Vala.
