The insistence of a lot of smart (?) people on NOT using whitespace for logic purposes is THE most baffling thing in the IT space. And I mean that.

If you look at your typical C-like code, it is already whitespace-oriented, you just manually add the braces as line noise, to make it easier to write a compiler for the language (although even that may not be true). It is like using one character variable names, which - other than the trivial places - makes your code harder to read.

If you want to write deeply nested logic in a function: well, don't. But if you insist, I'm not sure how curly braces help you in this case.
