I had a dream: codeunit references
Polymorphism is a great thing. .NET, Java, C++ and other folks have enjoyed its benefits for a long time, some more than a quarter century already. Meanwhile, we, the meager C/AL bunch, can only dream about it and draft our little patterns that all come short of it if only by a tiny bit.
Sometimes it feels like writing code with a chalk on a blackboard. There may be no end to your imagination, but there is a very real end to what the board can do for you.
But dream we can. And let me have another dream.
