What is the correct order when setting a POINT in MySQL?

Even the answers in SO questions differ on this:
[Moving lat/lon text columns into a 'point' type column](https://stackoverflow.com/questions/5756232/moving-lat-lon-text-columns-into-a-point-type-column)

Is it

```
POINT(lat lon)

```

or

```
POINT(lon lat)

```

As far, as i see it, it should be the first version (lat lon) as the POINT takes as params x and y, but i was not able to find an definite evidence.
