Say you want to write 'SET' now whenever someone sets a
width/height value for the rect (as an example), and 'GET' when
someone gets the width/height value for the rect, what you
could do is do this:
```
class Rect2D {
int rectWidth;
int rectHeight;
int width() {
writeln("GET");
return rectWidth;
}
void width(int rectWidth) {
writeln("SET");
this.rectWidth = rectWidth;
}
int height() {
writeln("GET");
return rectHeight;
}
void height(int rectHeight) {
writeln("SET");
this.rectHeight = rectHeight;
}
}
```
Honestly, it may not be a magic bullet, but still useful.
Yes, this is what I meant. I did use the UFCS name inaccurately:
I believe UFCS means the ability to write `y.x(z)` in place of
`x(y, z)`, and maybe the ability to write `y.x = z` in place of
`y.x(z)`, but it does not mean the ability to omit empty
parenthesis in a function call. The latter is what enables
getters that don't break the API.
