Add `-preview=safer` switch for safety checking on unattributed functions
|
|
|
|
All the checks currently enabled in `@safe` code, that are easily fixed (as in
|
|
the fix is constrained to the function), will be enabled in `-preview=safer` code.
|
|
|
|
Code not easily fixed, such as calls to `@system` or unattributed functions, will
|
|
be allowed as before.
|
|

void f();
|
|
@system void g();
|
|
|
|
void main()
|
|
{
|
|
int* p;
|
|
p++; // Error, pointer arithmetic
|
|
f(); // allowed
|
|
g(); // allowed
|
|
}
