Subject: [PATCH 2/3] Add tests for nullable numeric types CanBeNumeric
 property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Added test cases for int?, double?, and bool? to verify they are correctly marked as CanBeNumeric
- Verified existing implementation already handles nullable numeric types correctly
- Added experiment code to demonstrate the functionality

Fixes #22
