Hi, Thanks for the great module. We have been using it without issues until recently. Unsure if this is an intended effect, but dlocking a scalar whose value is 0 also locks $0 Module Distribution: Data-Lock-1.02 Sample Script: use warnings; use strict; use Data::Lock qw(dlock); dlock my $k = 0; $0 = 'test'; Output: Modification of a read-only value attempted at - line 5.

Thank you for your report. Fixed in 1.03. Immediately shipped to CPAN but if you can't wait it is also avialable at github: https://github.com/dankogai/p5-data-lock Dan the Maintainer Thereof On Fri Mar 07 12:41:07 2014, Ray.Kuo@hitbliss.com wrote: Show quoted text
