Plans to support VHDL 2008?

This is only a question Altera can answer (and they dont post in their own forums).

But Xilinx also do not support generic type parameters and functions either. (and their 2008 support is currently better than Altera's).

I suspect it wont come along until some big customers insist on it (which will probably never happen).

To be honest - most people are now moving SV for synthesis instead (like altera). it makes sense when all your verification will be in SV/UVM anyway.
