Update to “Delphi operator overloading: table of operators”: added the `in` operator

Posted by jpluimers on 2015/02/02

Because of Delphi sorcery: New dynamic array type in Spring4D 1.2, I updated this article from 2009: Delphi operator overloading: table of operators, names, and some notes on usage and ‘glitches’.

When I wrote the original article in 2009 the in operator wasn’t documented to be overloadable.

It is overloadable, and newer documentation includes it:

In addition I clarified a few things better (like not needing to return Boolean for comparison and set operators) and fixed a few typos and links.

The glitches are still there, so I’ve kept those.
