The idea of indentation defining structure seemed really cool when it
arose. I first saw it in a toy language called Henry, back in the early

But over time the notion that invisible characters define program execution
created so many problems that in retrospect it is ill advised despite its
prevalence. In fact its prevalence makes it even less advisable, as it
creates yet more areas for trouble.
