kotlinlang

Making an IntelliJ `FoldingBuilder` plugin for Kotlin (to "prettify" certain calls by changing their display), and I have a couple questions:
1. Is this the right way to check that a `KtSimpleNameExpression` uses backticks? `expression.text.startsWith('`') &amp;&amp; expression.text.endsWith('`')`
2. Would the following code properly detect if a library call is annotated, and would it have access to its annotation value, or do I need to do something more complicated?
```val reference = expression.mainReference.resolve() as? KtAnnotated ?: return
val annotation = reference.findAnnotation(PRETTY_FQNAME) ?: return
val name = annotation.valueArguments.singleOrNull()?.constValue as? String ?: return```
In particular, I'm not sure if `resolve` works for a library (i.e. not local) call, and if it works, I'm not sure if the `annotation` can be found with its value argument intact
