 code the first time after these are set. Thus, I recommended that you only rarely change the default context.

 **NOTE:** If you set `@default_checked`, some operations that expect the Julia default of unchecked arithmetic may not work. Particularly hash functions.
 I've included here a number of such core Julia functions and applied the `@unchecked` macro to them so that they still work. If you encouter an error in
