带参数的条件复杂

Question

if @near.nil?
  loc, @near, found = get_user_geolocation
else
  loc = GeoKit::Geocoders::GoogleGeocoder.geocode(@near)
  found = loc.success
  @near = loc.full_address
end

在第一个if部分,发生了什么？我的语法可能不太好,但它让我很好奇.提前致谢.

请参阅多个分配

> a,b,c = [10,20,30] # or a,b,c = 10,20,30
> a => 10 
> b => 20 
> c => 30
