An internal test verifying that an expression remains tied to its original context, even after the context has been cloned and modified.

ID: 606

See: uCalc = [uCalc] 
				
					using uCalcSoftware;

var uc = new uCalc();
// Internal Test: Context integrity after cloning
var baseUc = new uCalc();
baseUc.DefineVariable("x = 100");

// Clone the base instance and modify the variable in the clone
var clonedUc = baseUc.Clone();
clonedUc.Eval("x = 200");

// Parse an expression in the original base context
var baseExpr = baseUc.Parse("x");

// 1. Verify the expression evaluates using its original context's value
Console.WriteLine($"Base expression evaluates to: {baseExpr.Evaluate()}");

// 2. Get the parent and verify it is not the cloned instance
Console.WriteLine($"Parent is not the clone: {baseExpr.uCalc.MemoryIndex != clonedUc.MemoryIndex}");
				
			
Base expression evaluates to: 100
Parent is not the clone: True
