Like any templating engine there's always just enough power given to have the ability to write something stupid or complex in the template. Again not really a problem in practice.

The scary underscore expression you're referring to can easily just be written as a reversedList variable in "normal" JS and get referenced plainly in the template. So the template expression syntax never has to be as messy as you might think it is.

The "scary underscore" expression isn't scary because it's an underscore, it's because it implies the evaluation of JS, such that you could (and obviously wouldn't) do things like

    v-for="x in console.log('hello world!') && fetch('/') && [1,2]"

(my syntax might be off since I don't use Vue, but the merit should still apply)

My point is that when your templating language starts doing things like this (and inevitably, all of them do) - you've created a new programming language that is generally less thought out as one than deliberately made programming languages. Although the above for loop is evaluating JS, the syntax is decidedly not JS.
