- Pointers actually looking like pointers:
>. Example:>pointerVar. Pointers are safe by default but "safe mode" can be turned off to allow advanced programming. - Storing variable in other places than RAM:
$()or$. Example:$('path/to/dir')diskVaror$diskVar. Omitting the paranthesis will result in the compiler choosing where in the disk to store the variable for you. - Faster ways (typewise) to iterate through arrays:
arr[start_pos ... end_pos]. Example:arr[0 ... arr.length] == "something". Another example:factorial *= numbers[15 ... 2]would store the factorial of 15 in the variablefactorialif the arraynumberscontained numbers starting at 0 and then up to atleast 15. - Garbage Collection, can be disabled by passing arg.
--nogcto compiler. It will still work if you've manually collected most garbage, and can collect the ones you missed, but might increase the compilation time. - Channels & something similar to Go's goroutines.
