In addition, cgo calls are often reeely slow. I've been using the sqlite bindings to go for projects recently. sqlite doesn't allow you to write your own in-language functions, but instead allows you to write your own callback. I recently did some benchmarks, and the golang callback for a simple function was 20x slower than implementing it in C (1600us vs 80us), presumably due to all the marshaling and reflection required.
