Data::Locations

This version fixed an offset problem in the test suite related to the fact that self-ties increment the refcount in some Perl versions and not in others. This value is now auto-adjusted. A warning was included in Makefile.PL to state that Perl versions between and including 5.6.1 and 5.7.0 are not fully supported.

This version fixes the test script "02___refcount.t" for Perl versions 5.8.5 and higher. An offset varies from Perl version to Perl version depending on whether self-ties increment the refcount or not.

Fixed a bug in method "read()" which prevented empty lines to be
read back in list context (empty lines were mistaken for the
end-of-file marker) and when an item in a location has the value
"undef", the method "read()" now returns the empty string instead.
You would have mistaken this for the end-of-file marker in
previous versions.

All global or "class" methods are gone, all locations are local
variables now in the sense that they are automatically destroyed
whenever your last reference of a location goes out of scope, all
locations are dumped automatically now at shutdown time of this
module if and only if a filename has been provided previously, the
method "toplevel()" cannot be used to artificially set or reset the
"toplevel" status of a location anymore and the code in general, the
regression test suite and the documentation have been overhauled a
great deal.

Version 4.3 is mainly a bugfix release. The bug that caused
statements like ``print $location "text";'' to fail in Perl
5.005 is now fixed. Moreover, little improvements of the
code and a small regression test suite (for "make test")
have been added. Locations continue to be global variables,
though. Truly local locations are planned for version 5.0
(which is currently under development).
