Checking Typing
When data objects are assigned to typed field symbols and actual parameters are assigned to typed formal parameters of procedures, the system checks whether the data type of the assigned data object matches the typing of the field symbol or of the formal parameter.
General rules for typing
Special rules apply to:
Return values of functional methods
Literals as actual parameters
Functions and expressions as actual parameters



Latest notes:

When specifying data objects suitable for a typing, an assignment to a helper variable with a valid data type is often made. When methods are called, these helper variables can often be spared by using a constructor expression in the position of an actual parameter.
