def initialize(file:, line:)
  # Ruby 3.3 adds automatic definition of source location for evals if
  # `file` and `line` arguments are not provided. This results in the source
  # file being something like `(eval at /path/to/file.rb:123)`. We try to parse
  # this string to get the actual source file.
