Dead code should be removed

Jump statements (return, exit, continue, and raise) move control flow out of the current code block. Typically, any statements in a block that come after a jump are simply wasted keystrokes lying in wait to confuse the unwary.

Noncompliant Code Example​

begin
  raise my_error;
  log('finished'); -- this code will never be executed
end;

Compliant Solution​

begin
  raise my_error;
end;
