I accidentally wrote this while taking the train home from Stenungsund today:

Pete, Pat, Joe and Matt
Worked on some Delphi code
On a TreeView branch they sat
But couldn’t find a node.

Up spoke Matt and Joe
Explained, Items must be nil
Pete and Pat said “No,
It’s allocated still.”

Pete and Pat then found
A pointer that was weak
Joe and Matt, they looked around
Fixed a major memory leak.

Pete, Pat, Joe and Matt
Worked on some Delphi code
On a TreeView branch they sat
And Items[0] was a TTreeNode.
