There's also F#, CoffeeScript, Yaml, Sass/Stylus, Haml/Jade and several others, just among the popular languages.

And if we mean "significant whitespace" as in "newlines can act as statement and expression terminators" (since we were discussing semicolons as the alternative) we can also add a ton of other languages, like Ruby, JavaScript, Go, Scala, Visual Basic and Lua.

I don't think it's fair to compare markup languages to programming languages, so we're down to F# and Coffeescript. That's not much of a trend toward significant whitespaces.

I agree with newlines vs semicolons (though I've always been told to write Javascript with semi-colons, and that's how I have encountered it in the wild).

I take your point about Haml, though Sass is actually Turing-complete, so I almost feel like it belongs in the list despite being really off-the-wall.

And I was only choosing from reasonably popular languages (so things like Boo are out even though they'd help my numbers). There just aren't that many mainstream programming languages out there. Four in a category seems like a pretty fair number to me. You could just as easily say functional programming isn't a thing if four mainstream languages is considered a paltry showing.
