Alexander Ljungberg b53616ead3 New: @deref(<any idempotent expression>).
This change makes it possible to @deref any expression, such as a conditional expression, as long as the expression doesn't have side effects.

The reason not to allow dereferencing of expressions with side effects is that we might need to evaluate the expression twice in certain uses of deref, which is not obvious when you look at the deref operator in plain code.
