[sv-ac] 966 discussion

Hi All,

On second portion, I favor "any integer type and $ is preserved in type
conversions" since:
 - integer type restricts integral type to remove the packed types (and
bypass that "operation").
 - The preservation in type conversion is effectively same as $ being an
untyped parameter given that no arithmetic is allowed.
 - keeping type (also not limiting to int) does not overly restrict
passing when the actual can be $ but other things as well.

966 - last statement in the proposal should be changed to "cannot
be used as an operand in an expression". Need to resolve the issue of
a parameter type in Section 6.3.2.1. Should it be
- any integer type and $ is preserved in type conversions?
- an untyped parameter only?
- a paremeter of type int?
- other?
The exmaple should break the if statement into two: first to check for
$ using $isunbounded, and if this is not the case check for other
values in nested if statements.
