There were plenty of blanks in their thoughts.

I will take YAML's string blocks where I don't have to escape special characters over JSON any day.

It's to make students actually format their code correctly

...that modern systems should stop sucking at parsing leading whitespaces.

They are alright, yaml problems are overblown, significant whitespace as well.

I don't really have a solution for the whitespace issue, but you could always switch to TOML

Significant whitespace is the best! I don't understand why so many people have issues with it.

Fussy.
