I as well find Go interesting and good.

I've written a non-trivial program in Go, and rewrote it a year later in C.

In Go, the binary size (statically linked) was 2.9 MB - when it ran it
had a max of 3.1 MB of RAM resident.

C, of course, was better. 59 KB statically linked against musl, 600
KB resident. The runtime is faster too, but that isn't directly
comparable, as the C version uses a better algorithm.

With that said, I continue to enjoy Go. 2.9 MB is frankly not that
large, and it was fun and easy to prototype in.

To be clear - I don't support rewriting system utilities in Go. *base
are starting to look nice, and statically link down to a very small
size. I don't see any wins in rewriting these in Go.
