Hello everybody,

I'm using unit testing not only for testing my own code, but I also find it a great source for documentation. 
When I'm going to use some third party module with my own projects, I give a look at its unit tests. They are full of examples how the module behaves. Examples witch aretested to work, and  never out of date. 
Unfortunatly the assert_equal notation makes those examples pretty hard to read: 

    assert_equal("Some result", object.method(parameter, etc))

At other places (p.e. http://www.glue.umd.edu/~billtj/ruby.html) I found the following notation for examples: 

    object.method(parameter, etc)        # -> "Some result"

I think it would be very helpfull to introduce a new operator '->' such that 

    object.method(parameter, etc)        -> "Some result"

can serve as an easy to read example and as a runnable test. 

Bye, 
Markus Schmaus.
