Core of Sudoku Puzzler is ported without input error detection (no try/catch statemen...

Lessons Learned
1)  There are fewer implicit type casts with our compiler.
2)  Error Handling
2a) Functions that could throw an error but does not return anything can return a boolean to check for errors.
2b) Functions that do return something can return either a null (if returning an object) or an invalid value to check for errors.
