 ### Unsigned integers
 
-Nim strongly discourages the use of unsigned integers, as it's considered unnecessary and somewhat unsafe* for most applications. The unsigned types uint, uint8/16/32/64 are available by default, but the arithmetic and binary functions are not defined. If you do need to do arithmetic on unsigned integers, you need to import the **unsigned** module.
