Which is why the current JSX syntax uses that as a synonym for `disabled={true}`. Agreed that it matches HTML better, but having written an awful lot of `someLongVariableName={someLongVariableName}`, I sure wish I could stop repeating myself there.
I, too, find it ridiculous to repeat `foo={foo}` over and over again. So I use the spread operator with ES6 shorthand object syntax. Now it’s `{...{ foo }}`. No breaking changes needed!
