I've landed my first compiler PR for golang/go 🎉
It optimizes `[]byte(str1 + str2)` conversions by making them a single step instead of first concatenating the string and _then_ copying the result in a new slice.

Admittedly, it really took handholding and patience from the Go team there, which I really appreciate 😅
On to the next one!
