Could we support something similar to nim's compilation option pragmas [1]:

```
{.push checks: off.}



```

in D could look like:

```
pragma(push, "-noboundscheck -O -release");
// compile this section with specified flags as it's critical
pragma(pop);
```

That approach has a number of problems.
Basically the optimizer works at module scope, I'd be difficult 
to constrain it's use.
Secondly what happens if conflicting options are nested ?
