You need three keys or two keys and a long hand movement to type C++, but you only need two keys for 'go' - and the keys for go are alternate hands and strong fingers, but even the nearest + symbol requires a weak finger or a contortion.
Also, go is typed as a typical word more often than ++ is, so it's more habitual and familiar and automatic.

I suggest it's much faster.
