// The tests in examples_test.go are the ones that are not architecture dependent
// The tests in examples_32bit_test.go are for 32-bit systems
// The tests in examples_64bit_test.go are for 64-bit systems
//
// The architecture dependent files cover the difference when dealing with [safecast.ToInt]
// The error message is different on 32-bit and 64-bit systems
// The max is 9223372036854775807 on 64-bit and 2147483647 on 32-bit
//
// The examples could have been skipped for 32-bit systems,
// but I wanted the Examples to be launched on this architecture.
