Bug #89597 for Devel-REPL: Persitent Context not cleared

Hi, I found a bug while using a module that uses Devel::REPL for its command shell and the maintainer indicated that I should forward the issue on to be resolved. A summary would be that I would set a variable using 'my @x' and even though it was not set initially, it would have a set of values. I tried this several times and then also with the perl command line which worked as expected. The below email thread explains in more detail as well as the finding from the PDL module maintainer. Devel::REPL version is Devel-REPL-1.003025 via cpan with Strawberry Perl 5.16.3.1 32 bit on Windows 7 Enterprise 64 bit. Let me know if you have further questions. Thanks, Cliff. Hi Cliff- It is an edge case where the lexical variable is not cleared in the persistent context and the problem is visible in the Devel::REPL shell and not just pdl2. I'll take a look but definitely worth a bug ticket until it is resolved. The behavior may be consistent with the current implementation---but I think it should match the perl script/program result when ever possible. --Chris On Wed, Oct 9, 2013 at 11:48 PM, Clifford Sobchuk <clifford.sobchuk@ericsson.com<mailto:clifford.sobchuk@ericsson.com>> wrote: Hi Folks, I received some unexpected results when using 'my' in the pdl2 shell. I verified that the correct behaviour works from perl -e, but I am not sure if this is a pdl2 shell problem or a Term::ReadLine problem. Thanks Cliff. I tried the following code: Show quoted text
