You said this: "Well, depends on how we define narrow ... you are writing probably this email on a HDL designed machine ... and the entire world is powered by HDL designed silicons. that is not small for me at all." Which I take to mean that because there are billions of chips in the world there are billions of python users.

There is a reason that there are 1,000s of computer languages in the world. Not all computer languages are able to solve all problems. If Chisel or Scala is closer to what you want why are you not using them for your HDL tools? > And what is the problem python solves that C doesn't solve? > And what > is the problem C solves that assembly doesn't solve? > One common answer > to all of them would be: fewer chars for bigger ideas.

And it seems that you have hit a major problem with the HDL syntax not mapping to python.

Packages like numpy are not written in python for a reason. A pure python numpy would be very slow. So yes we worry about run time speed. Barry
