There was a problem hiding this comment.
This should be fine, but we try to avoid using lvalues more than once. The main exception is for method calls, where we evaluate the receiver to an lvalue, then use that lvalue to load the property for the method and again as the receiver of the method call instruction.
To test, can you add some fixtures where the increment/decrement is used as an rvalue? let x = obj.x++ and (obj.x++).toString()
