Go Tour example 29 contains the latitude and longitude of Bell Labs. They are stored in
a Vertex type defined as:
type Vertex struct {
Lat, Long float64
}
and given as:
Vertex{
40.68433, 74.39967,
}
This is all just fine. Works fine, is a cute homage, etc. However latitude is
interpretable as north or south and longitude as east or west, and only one of these
combinations maps to New Jersey.
A subtle change would be to retate the type definition as:
type Vertex struct {
Lat, Long float64 // North,West
}
That will guide curious readers to the intended location:
