Quixote's Page Template Language uses this form, but only supports a single decorator chosen from a restricted set. For short lists it works okay, but for long list it separates the argument list from the function name. OTOH, for long argument lists, the "preferred" form has the reverse problem: the decorators are separated from the function name by the long argument list. The question then becomes, what is more likely: long argument lists or long lists of decorators? I know that (at least in certain code bases :) long argument lists are common. Will long lists of decorators ever become popular?

I don't think so. Although even a single decorator may be a function taking quite some arguments.
