I think it might have a bug or two yet. Perl is reference counted and Go is garbage collected. Keeping those two synchronized was a bit tricky and I still fear I messed it up somewhere... I need to re-read the Perl docs on when I'm supposed to up & down the Perl refcounts.
Perl's behind the scenes C code is rather gnarly. Trusting a new tool to get it right the first time is a bit much. Once I'm comfortable it's had some time to age properly, I'd be more than willing to deploy it.
My C days was a long time ago, but this looks like simple and elegant stuff to me. What would be the problem with production code? The Go language?
