I hate erroneous error messages. Like benign warnings. They only serve to hide true problems. Like doing a testcover on a module, seeing that you're only getting 63.2% conditional coverage, and then noticing that one of them is for code like this: 

  my $var = $opts->{foo} || $self->{default_foo};

[download]
when $self->{default_foo} is very carefully never allowed to be bad (a default provided in new, and the setter function not allowing bad values, including no value). And then Devel::Cover posits:
86367
ABdec
000
011
1X1
my $var = $opts->{foo} || $self->{default_foo};
(I can't use "style=" attributes, but the 0 0 0 line shows up in red because it's not being tested.) Is there any way to turn off that row, or otherwise tell Devel::Cover to ignore that possibility because I, as the human, have concluded it's not possible to reach?

Update: I guess I should read the TODO file: 

  - Marking of unreachable code - commandline tool and gui.

Not entirely sure how said tool would work, but that's the basic idea. I kinda like my comment idea better - because I'm much less likely to lose checked-in code than the cover_db database, where I presume the "unreachable code" will be remembered.
