Delay recognition problems

[libbkmz]

Hi, I try to parse cell library, and getting error near delay statement. Here is example:

test.v:

module MODULE_NAME(Q);
    not #(1) (Q);
endmodule

main.py:

from pyverilog.vparser.parser import parse
lib_ast, lib_directives = parse(["test.v"])

And I got this Traceback:

λ python main.py
Syntax error
Traceback (most recent call last):
  File "main.py", line 7, in <module>
    lib_ast, lib_directives = parse(["test.v"])
