My experience was that I would have an idea for a new model and change my code. Later on I would find that new model would be flawed, but only after fixing compiler type errors in many different places when all I really needed to find was that one error that showed my model was flawed.
I should add that itβs heartening Pike actually acknowledges this in the interview, regarding limited typing and how it helps playfulness in languages like Python and Ruby.
That's fine, in most cases, writing python code, you find out that you fucked up when you run the script. Compiler errors catch whole classes of errors that you ordinarily wouldn't find unless you ran the code.
