Test, validate and match regular expressions
Matches object instantiation statements like `obj = new ClassName(args);` commonly found in Java, C++, C#, PHP, or JavaScript code. It captures a variable name, equals sign, the 'new' keyword, a class name, and optional constructor arguments inside parentheses, with flexible whitespace and an optional trailing semicolon. Useful for parsing, validating, or extracting single-line object creation assignments from source code.
