You can store an object instance in a Slim symbol and then use the instance in parameters for methods or constructors.
Here createTestSlimWithString(string) is a factory method that creates a new !-TestSlim-! instance, sets the given string and returns the object.

The boolean isSame(Object other) method returns whether the other object is the same as the current !-TestSlim-! table actor.
The !-getStringFromOther(TestSlim other)-! method returns !-other.getStringArg()-!.

!|script             |test slim                                             |
|$TEST_SLIM_INSTANCE=|create test slim with string|Uncle                    |
|check               |get string arg              |null                     |
|reject              |is same                     |$TEST_SLIM_INSTANCE      |
|check               |get string from other       |$TEST_SLIM_INSTANCE|Uncle|
|check               |return constructor arg      |0                        |

!-TestSlim-! has a constructor !-TestSlim(int, TestSlim)-!

!|script                                            |
|start |test slim             |1|$TEST_SLIM_INSTANCE|
|check |get string arg        |Uncle                |
|check |return constructor arg|1                    |
|reject|is same               |$TEST_SLIM_INSTANCE  |

An instance stored in a Slim symbol can also be used for instance chaining (ChainWithInstanceTest).
