The main reason I love Go is because it makes me feel like the more I use it, the more I'm able to do and get it done faster. When I solve a given problem, it's solved for all my current and future projects written in Go.

When I was working with C++ earlier, that was not really the case. After spending many years with it, I couldn't write a simple web server in under 5 minutes. Making something into a library had too much overhead. In Go, once I've done something [1], the next time it's one line to import it.

Also, working with the language programmatically is a pleasure. There's a full parser in the standard library.
