Yes, this is my argument against significant-whitespace languages like python, or even worse for simple nested data like yaml.

Actual delimiters explicitly structure your code, and then automatic formatting confirms it, kind of like double-entry book-keeping.

For me, just a couple of days with lisp and parentheses made me wish every language had such simple explicit syntax, I really recoil at some language's special syntax, eg python list comprehension. Maybe I just hate python, lol.
