```suggestion
lldb_private::dil::Token token =

0);
```
(The reason is that this looks like a test for the token kind testing
functions. You don't actually need the token to come out of the lexer for that.
And we already have tests that check that producing a sequence of characters
produces an "identifier" token.)
