Brainstorming: quoted identifier operator

Hi,

just another idea based on my everyday work - let's defined new quoting
operator: quoted identifier.

Let's say it will be `qi`.

Where it can be used?

For example class based test frameworks - where method is a test case:
```
sub qi (this is nicely readable test name) {
}
```

I can imagine web handlers like:
```
sub qi (/user/:id) : GET {
}
```

What do you think about this?

Best regards,
Brano
