foo.pl:

method foo { return }
method bar($something?) { return }
method quux(:$file, Bool :$debugging = undef) { return }
PACKAGE->foo;
PACKAGE->bar;
PACKAGE->quux;

cover -delete ; perl -MDevel::Cover -MKavorka foo.pl ; cover

Coverage should be 100%, but is only 77% because of the extra code generated to handle signatures etc. In a larger project, this extra code is an amount of noise among the test gaps in my own code. So I propose that by default Kavorka should annotate its generated code to exclude it from coverage: http://p3rl.org/Devel::Cover#UNCOVERABLE-CRITERIA

Inserting comments is problematic. Perl comments are terminated with a line break. Inserting line breaks screws up the line numbers in error messages and warnings.

Is it not possible to achieve 100% coverage by testing the variety of signatures accepted? IMO this is how coverage should be working anyway though I suppose it is technically testing Kavorka rather than the code in question
