Go developers like to claim that the reason the Go compiler is fast is because it's "simple to parse". Unfortunately this doesn't make a lot of sense as parsing is typically only 1-5% of the total compile time.
It's not only about the main compiler. Go has tons of third-party tools (linters mainly) that can parse go code, because it's so easy to write one. Most of them wouldn't exist if parsing was a PITA.
