Enum member `std.traits.isSafe`

				enum isSafe(alias func)
				 = (functionAttributes!func & FunctionAttribute.safe) != 0 || (functionAttributes!func & FunctionAttribute.trusted) != 0;

Example

@safe    int add(int a, int b) {return a+b;}
@trusted int sub(int a, int b) {return a-b;}
@system  int mul(int a, int b) {return a*b;}

static assert( isSafe!add);
static assert( isSafe!sub);
static assert(!isSafe!mul);
