Presumably it’s because TypeScript, ActionScript and Hack already use the function foo() :
type form, so it’s a familiar syntax. However, Go uses the func foobar() type
form, so there’s also precedent for that one. Considering the audience of PHP, TypeScript,
ActionScript and Hack are probably more familiar than Go.
Maybe there’s a technical reason for it, though.
