How many GC's do we get, if we build a D application linking it to a D
library statically, or dynamically, or by loading it at runtime?
It seems to me, that one thing people really want in this discussion is to
be able to select a single allocation strategy for their application,
regardless of the libraries involved.
Is this at all technically possible?
I realise that if we had ARC, and GC, and manual memory management as 3
possible strategies on the table, and given that each would require
different code/annotations then a library may be written for only say GC
and simply wont work in the other modes.
But, could we design a system such that DMD can determine what allocation
strategies are valid for a given library at link time. It would require
that libraries advertise this (in a separate file if necessary) although
presumably they would or would not contain the required hooks as exported
symbols for ARC or manual free if not built to support them so link would
simply fail.
I admit I am not well versed in the details, but conceptually this could
be powerful and flexible...
