描述
Another follow up after https://github.com/scalameta/metals/pull/4776.
There's need to pass every constructor argument as a function in scala.meta.internal.metals.Indexer and scala.meta.internals.ScalaCli
- Usually, replacing
() =>, should be straighforward change, but sometimes() =>was used to capture mutable state. - probably
IndexerandScalaCliaren't the only ones which can be refactored. Person doing this task can browse other classes (optional)
