RE: [sv-bc] nettype

The second derivation rule of a nettype declaration is to create another name for an existing nettype. However I believe it applies to user defined nettypes only.
 
net_type_declaration ::= // from A.2.1.3
nettype data_type net_type_identifier
[ with [ package_scope | class_scope ] tf_identifier ] ;
| nettype [ package_scope | class_scope ] net_type_identifier net_type_identifier ;

No i want simple feature equals to what can I do for data types.
Ie I want do declare a net with a data type and predefined net type

wire logic [3:0] w;

Assume that I'm using such pair in many places and I want to change the net type - to do so I would have to find each interesting occurrence and do the change is I could :

typedef_net wire mynet;
typedef reg[3:0] mytype;
mynet mytype w;

then all I need to do is to change mynet declaration.

Same idea like for types
