And because they are competing standards, they also reduce in numbers over time.

#7Opa is neat, but the two license options of AGPL or "talk to us for a price" basically ensure it will never achieve anything close to mainstream usage.

#8It's a herculean effort. I heard about Opa about a year or two ago, amazed he's still at it. Kind of like Haxe. I doubt they will go anywhere, like Coffescript, because any language that simply abstracts another is just cruft and doomed to be obsoleted.

IMHO the CoffeScript analogy is a poor one. CoffeeScript actually abstracts very little from the JS base, being mainly about a lighter-weight, more productive, more enjoyable syntax. Opa is far more ambitious in its abstraction.

By that logic, Ruby and Python are just as doomed because they're ultimately just elaborate abstractions on top of C (or at least their reference implementations are). The implementation language and output target of a programming language are not material to the language itself. C targets a wide array of machine codes, but you'd be remiss in saying it's "just an abstraction on top of x86," and thus doomed to fail. Likewise, Java can target JVM bytecode or Dalvik, but it is not "just an abstraction" on top of either of those. Clojure can target a dizzying array of output languages — JVM, CLR, JavaScript, Scheme, Lua, Python…
It just boggles my mind that because a language compiles to JavaScript, it's "just an abstraction on top of JavaScript" or "just sugar" or whatever. Like if you took the same language with the same semantics but didn't target JavaScript as your object code, the language would become more legitimate. How is that in any way a useful view of the world? Is Clojure also just an abstraction on top of JavaScript because it can target JavaScript?
