Unsafe

Have you ever been annoyed that Ruby prevents you from accessing out of bounds elements from Strings or Arrays?

unsafe unlocks the full potential of your Ruby programs by allowing accessing and modifying out of bounds memory!

$ gem i unsafe
$ irb
>> require "unsafe"
>> arr = [1,2,3]
=> [1, 2, 3]
>> unsafe { arr[1] }
=> 2
>> unsafe { arr[2] }
=> 3
>> unsafe { arr[3] }
=> 2.000000000000003
>> unsafe { arr[-1] }
=> Array
>> unsafe { arr[1000000000] }
[BUG] Segmentation fault at 0x00000002f89824d0
