it's about as fast as it can get, as long as you only call compile when
the expressions change. (the example didn't show it, but the "expr"
code object can of course be reu
Thank you! this "compile/exec in context" is the thing i wanted.
It is not that performant i think. But it should ease the prototyping.

I'm probably to lazy to write my own parser.
I have such a statement as string: "distance = x**2 + y**2"
x and y are undefined, so it is no executable Python code, but it is
parseable. Now i'd like tra
