Why do I get this process::state irun error?

Playing with SystemVerilog, I'm trying to get the status of some processes that are forked. In order to do that, I create a variable where I can get state of a process. From part 9.7 of 1800-2012 SV-LRM:

process::state pstat;

But I get the following error with irun:

xmvlog: *E,EXPIDN expecting an identifier [3.2][3.8][3.9(IEEE)].

state is an enum type embedded in a class. The BNF does not allow you to use it directly, but some tools allow it. You should be able to do:

typedef process::state state_e;
state_e pstat;

// or
type(process::state) pstat;

state is a method of the class process. You can't create a variable of type process::state - that makes no sense. There is an example in section 9.7 of IEEE 1800-2012, which shows how to use the process class.
