CAVEATS AND LIMITATIONS

BEGIN blocks

The fork() emulation will not work entirely correctly when called from within a BEGIN block. The forked copy will run the contents of the BEGIN block, but will not continue parsing the source stream after the BEGIN block.

Which may or may not be relevant to IPC::open3 (which must do an emulated fork under the covers), but as I just re-read this a few minutes ago, I thought it worth mentioning. You might be better off using an INIT block rather than a BEGIN block.

Examine what is said, not who speaks.
"Efficiency is intelligent laziness." -David Dunham
"When I'm working on a problem, I never think about beauty. I think only how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong." -Richard Buckminster Fuller
If I understand your problem, I can solve it! Of course, the same can be said for you.
