Default value of dynamic array argument in SystemVerilog

Question

According to SystemVerilog LRM 3.1a (p.38) it is possible to pass dynamic array as an argument to tasks of functions:

 task foo( string arr[] );

Is it possible to assign a default value (zero-sized array) to this argument? Somewhat like we can do with other arguments:

task foo2(int i = -1, byte z = 0);

Finally found an answer. It is possible to do C-like array init at declaration time. Looks like:

task foo ( byte bar[] = '{} );

By the way, it seems there is no mentions about this possibility in LRM.

The 3.1a LRM is really old and out of date. Take a look at the latest which is publicly available. stackoverflow.com/questions/16399064/…

Out of date compared to the SystemVerilog implementations that are out there? My impressions is that the LRM leads the implementations by a long ways and using an older LRM might actually represent what your tools are doing more accurately.
