Brad,
Seems that your changes for package scope resolution have
rippled into section 4.6.1:
"dynamic_array_new ::= // from Annex A.2.4
new [ expression ] [ ( dynamic_array_variable_identifier expression ) ]"
It would seem that this means that we can now do more than
just the array variable identifier. If the only thing we
can now do is pkg_name::array_identifier, perhaps that should
be noted. Or can we now do a slice of an array, etc. (I don't
think so)?
Also, the paragraph following the new syntax becomes very confusing
since we no longer have "dynamic_array_variable_identifier" in the
bnf:
"Optional. The name of an array with which to initialize the new array. If
src_array it is not specified, the elements of array_name the newly
allocated array are initialized to their default value. src_array This
array identifier must be a dynamic array of the same data type as
array_name the array on the left-hand side, but it need not have the same
size. If the size of src_array dynamic_array_variable_identifier is less
than size the value of the expression, the extra elements of array_name
shall be initialized to their default value. If the size of src_array
dynamic_array_variable_identifier is greater than size the value of the
expression, the additional elements of src_array shall be ignored.
This argument is useful when growing or shrinking an existing array. In
this situation, src_array dynamic_array_variable_identifier is array_name
the same as the left-hand side, so the previous values of the array
elements are preserved. For example:
"
At places here we refer to expression, but now we have two expressions,
so we need to differentiate the size expression from the name expression.
Also, we refer to the identifier, but that's no longer in the bnf.
Can you help clarify the intent? I could guess and make some changes...
