Subject: stat() can also return no arguments if the file can't be found. Hopefully, our %ops... 
X-Git-Tag: v0.02~8
X-Git-Url: http://git.vpit.fr/?a=commitdiff_plain;h=2d8aec84852aa584b41d7cfce42088fec7ca8582;p=perl%2Fmodules%2FSub-Nary.git

stat() can also return no arguments if the file can't be found. Hopefully, our %ops hash can also hold probabilities of return. Make sure that it's duplicated when returned
