RE: [sv-bc] 10.8 Named blocks and statement labels - question

initial #10 outer_label.inner_label.V = 5;


The 'while loop' is a single statement that has as part of it an inner
block statement within it. That outer statement label is attached to the
entire while_statement.

I agree that the LRM could be improved on this matter and wish I had the
time to improve it. So someone, please come up with a proposal.
