This is OK.

This is also OK.  Just for the record, I first thought that your two
tests where still the same and thus would generate the same message.
But after a closer inspection, one used $a++ and the other ++$a.
Why not use something more different like '$a * 2' maybe?

Another way to make things different is to specify distinct messages
explicitly - for instance "first eval" / "second eval"...
