I am happy user of FreeNAS (a great open source storage server solution) and sporadically follow its development. A couple of months ago, William Grzybowski committed revision 22ebffb6 to the FreeNAS code repository. He crafted a lovely commit message:

Dear perl, You’re very brave, you have been fighting against us for a long, long time.

The time has come to tear you apart and bury you very deep. Rest In Peace

Indeed, the FreeNAS team chose to build their management system on top of CPython (2.7, in this case). A great choice pro development efficiency and pro community efforts, I guess.
