Chris,

Any workaround is a good as any other workaround, but still is a 
workaround. I just added the 4 (in my actual module, not the example) 
constants in the call. 
None of the workarounds can be classified as _pythonic_, I'd say. What 
if I come up with a 8 * 8 constant matrix (like in JPEG DCT)? And it is 
well supported in VHDL ...
I checked the _toVHDL code and process (I built a lot of tracing in my 
local copy), and it is not evident how to add support for this. But 
we'll discuss this another time? (It's bedtime over here ...)

Best regards,

Josy
