Allow INIT clause on the DEFINE ALIAS statement

It could be beneficial, when defining an alias, to define as well a default initial value. When this alias is used in a variable declaration, this initial value would be automatically applied.

Example:

DEFINE ALIAS CASH_AMOUNT DEC FIXED(18,2) INIT(0);

DECLARE MY_AMOUNT CASH_AMOUNT;

Variable MY_AMOUNT would be implicitly initialized to 0.

    While this would be tempting, DEFINE ALIAS is supposed to define a data type and INIT isn't a datatype (as all the other storage attributes are not either). INIT isn't allowed in a RETURNS description either for similar reasons

    Isn't INIT always an operation that has to be coded explicitely? I don't see why i want an implicit INIT on aliases.
    But support for VALUE(:TYPE:) might be a good idea, as the developer doesn't have to know if it's an ALIAS or DEFINED STRUCT that's behind a TYPE.
