| Subject: | format_write and I/O operator write don't work |
Using perl's formatted output functions with a file handle such as IO::Lines does not work. When using the I/O operator write, a warning about writing to an unopened filehandle is output. When using the OO syntax, no errors or warnings are produced. In both cases, the output never makes it into the array.
Please see the attached code that reproduces the bug, and email me if you have any questions.
