My point wasn't that Mustache lacks these features, but that they're so essential as to make not handling them well feel like an omission. It needlessly bloats your template code to have to write within these constraints, and for what benefit? Some nebulous ‘logic-less’ purity?

But it does have those features, so, I don't get it. What are you trying to say?

As for bloated template code? I really don't know what you are talking about. Perhaps you just haven't seen well written mustache templates. My startup, Bagcheck, and Twitter (where I now work) have switched completely to Mustache. It really does work well if you use it properly.
