Comment fix
Fix wrong use of PERL_SUBVERSION where it should have been PERL_VERSION
Handle lexical subroutines
Fix for skipping all tests
Add test for do STRING
Test map/grep/sort
Remove redundant restart_profile() method

It can be replaced by stop_profile() + enable_profile().
Allow calling enable_profile() after stop_profile()

It needs special treatment because stop_profile writes an end tag that makes
the aggregator discard state information.
Add sortable table from http://www.kryogenix.org/code/browser/sorttable/
Make all subs/all files tables sortables
Add method to list the report names for an aggregator
Add a method to remove some of the keys from custom metadata
Add per-report and per-aggregate metadata support

This adds the scaffolding (class definition, load/save code, ...) without
providing the actual functionality.
Support adding per-report metadata during aggregation
Optionally add @INC value to global metadata
If present, use @INC value stored in metadata to shorten file names
