Hi all,
I have been trying out to wrap my mind around the advantages of
decorators and thought I found a use in one of my experiments. (see code
after my sig).
Although it works, I think it should be able to do it better.
My particular problem is that I want to remove an argument (say always
round the issue aside from forking new
processes or using something else?
If you know that your (C) code is thread safe on its own, you can
release the GIL around long-running algorithms, thus using as many
CPUs as you have available, in a single process.

That's intentional, and not going to change. You can access the

In that sense, the encoding declaration only "matters" for Unicode
