As we know, all stylesheet values cannot be used in various places to add/combine styles (because they are int). Also we cannot use array() in stylesheets (runtime error).

Should we do something (at least try to) to avoid this kind of issue?

Maybe StyleSheet.create could returns Style.calculated so we cannot reuse those styles (& btw, flatten could only accept those styles ?).
That would make more complex the way we allow to use style in array for example but I wanted to give it a shot...

Also, in #520 we are saying that absoluteFill & absoluteFillObject are "the same" but they are not are one is a js object & the other is an int...

Thoughts?
