During the initial development of Geo::Point, I changed my idea a bit...
but there were some spots where I did not repair the changes. The
concept is to have only one projection definition per object.
Uptil the latest release, when you constructed a line from GeoPoints,
you got a line object which contained geopoint objects. But when a
line was constructed from x,y pairs, it was kept as such. This was
not acceptable. That got fixed, to behave as documented.
You could change your code into
my @points = $line->geopoints;
my $ax = $points[0]->x;
or better
my $ax = $line->geopoint(0)->x;
