A range can be a declaration/definition and a reference in C#

[dbaeumer]

Example:

public static implicit operator string(Program p)
{
    return "hello";
}

The word string is both the definition of the conversion operator as well as a reference of the type string

@daeumer are you working on a C# LSIF indexer?

[dbaeumer]

@chrismwendt no. I got this from a C# expert as feedback when reading the spec.
