Wouldn't you like to have adequate interpolation in php?

```
$index = 12345;
const SOMETHING = 333;

function number() {
    return 888;
}
echo "this is a ${{ number() + 123 * $index + SOMETHING }} string";
```

Personally, I find the interpolation we have "adequate", but you're not 
alone in thinking that a more powerful feature would be nice. Have a 
look at this recent thread for some of the possibilities and problems:

As a general note, though, it's best to broach new topics with a bit 
more thought than this - being able to say "I've looked into improving 
X, and it seems possible that it could work like Y, with possible 
problem Z; should I pursue the idea?" is going to get a more favourable 
reaction than just "wouldn't you like X?".

Regards,
