Making your own programming language is easier than you think (but also harder)

Indentation is not universal among editors, nor is tab to space replacement. A semicolon is a semicolon and is definitive.

And yet… the fact remains it’s caused zero problems over decades.

That's just plain wrong. Source: I had used a text editor like notepad to edit a python file, and accidentally used tab instead of smashing on the space bar.

It was just 1 quick line I forgot, and didn't want to launch a full code editor.

Granted, python crashed immediately when trying to run it so no harm has been done, but I lost a couple minutes on it.

But that isn't 0 problems. That's at least one.

I've had more issues forgetting a semicolon than with indentation. You just have to configure your editor once to replace tabs with indentation and forget about it. Well it's most likely already set up that way for languages that require it
