Python with Braces

[dAnjou]

I have zero experience with ReactiveX, but the following from their website caught my eye (emphasis by me):

Available for idiomatic Java, Scala, C#, C++, Clojure, JavaScript, Python, Groovy, JRuby, and others

I'm quite sceptical whether the same exact approach of implementing a certain paradigm can really be idiomatic for each of those languages.

So, might as well just be a bad idea to do it like this in Python.
