Arrays aren't really supported by SIP at all.


I get that...

You'd have to provide hand-written code that implements the sequence
protocol and proxies for the underlying array.


...and for N-dimensional array variable members of classes, I already
generate the needed %GetCode etc. Can you clarify what directives I could
use to "host" the generated code in this case, where the variable is not in
a class?

(Although as this case is const you could get away with creating a tuple
with the same elements.)


Acknowledged. But even for SIP_PYTUPLE, I'd need the same directives
wouldn't I?

Thanks, Shaheed
