This attribute allows the structure parsing code to be inlined instead
of being contained in a separate function.
This is helpful as variable are declared in the function so allows
other members to access to a nested structure.
For instance in this example MouseState structure text (ws_txt) access
pt member fields and needs the ws_inline attribute:
struct Point {
int32 x;
int32 y;
};
struct MouseState {
Point pt @ws_inline;
int32 buttons;
} @ws_txt("Mouse at (%u,%u) buttons %u", pt.x, pt.y, buttons);
