Angular lazy one-time binding for expressions
Yes. You can prefix every expressions with ::, even the ones in ngIf or ngClass:
<div ng-if="::(user.isSomething && user.isSomethingElse)"></div><div ng-class="::{classNameFoo: user.isSomething}"></div>Actually, the code simply checks that the two first characters in the expression are : in order to activate the one-time binding (and then removes them, thus the parenthesis aren't even needed). Everything else remains the same.
