Sure you can write some script to interpret the data, but then you need to write an extra script that you need to run any time you step through the code, or whenever you want to look at the data when it's stored or transferred.

But I guess you have never worked on an actually big project, so how would you know?

I guess you aren't entirely wrong here. If nobody other than you ever uses your program and nobody other than you ever looks at the code, readability really doesn't matter and thus you can microoptimize everything into illegibility. But don't extrapolate from your hobby coding to actual projectes.
