There is a functionality that allows you to convert an expression to a parameter.

When using local variables it occasionally happens that you wish to move that variable in a parameter (since for some reason it is dependent on the caller).  

The variable name is not an expression of the needed type, and using the assigment is cumbersome since you will introduce a new variable which cannot be named the same as the original local variable, requiring more work.
