There's a very simple explanation why the above code is suboptimal:
The second line does an *implicit* "Point new", which makes the first line
unnecessary.

It still is.

The point is that Point creation is such a ubiquitous operation that there
was a shortcut invented - the "@" operator on numbers. This hides the fact
that a new point is created, but most people prefer it over the longer
version ("100 at 100" vs. "Point new x: 100; y: 100").
