Hi I heard that you can pass a command line argument to make D
safe.
I don't think the command line argument is available anymore,
instead it uses a function level annotation @safe
So, on the function you want, you put it down and then that
function can only do memory safe operations and only call other
@safe, or manually verified @trusted functions.
To get it site wide, you can put it on main:
@safe void main() {
// memory safe function
}
Note that not all standard library functions are properly marked
@safe, so not all stdlib functions will be available. Notably,
writeln() in std.stdio is not marked safe... you can work around
it by making a @trusted writeln as described here
