The syntax highlighter not understanding GStrings (heh) doesn't help here.
It's obvious once you release that whatever is inside a GString is simply an expression.
```
    def expr = foo."${baz}"
    println("Bar value: ${expr}")
```
This makes sense.
But this, or any of the other variations...
```
    def expr = foo." + baz + "
    println("Bar value: ${expr}")
```
...does not make sense.
If the syntax highlighter understood GStrings, then this would be obvious.
Let S be string colour and _ be non-string colour:
```
    println("Bar value: ${foo."${baz}"}")
    ________SSSSSSSSSSSSSS____SSS___SSSS_
```
