Code samples of common sources of slowdowns for the Swift 2/3 compiler.

	//
	// The code snippets below showcase common "problem code" that can take a long time to compile.
	// These examples were primarily observed in Swift 2/3 and may no longer be relevant in Swift 4 or higher.
	//

	/// 1. Array concatenation
	// Observed by Robert Gummesson - https://medium.com/@RobertGummesson/regarding-swift-build-time-optimizations-fc92cdd91e31#c75c
	// Joining two arrays together with the '+' operator can be expensive to compile.

	let someArray = ["a", "b"] + ["c", "d"]
