        A builder type for Enso vectors.
 
-       Arguments:
-       - java_builder: The accumulator for the new vector.
-
-       A vector builder is a mutable data structure, that allows to gather a
-       number of elements and then convert them to a vector. This is
-       particularly useful when the number of elements is not known upfront.
-
-       There are two ways to create and use a `Builder`: `Vector.new_builder`
-       and `Vector.build`. `.build` is the preferred approach.
-       - `Vector.new_builder`: creates a new `Builder`, which you have to
-         "close" with `.to_vector` at the end to get your newly-created
-         `Vector`.
-       - `Vector.build`: takes a function which uses the `Builder`, and
-         automatically "closes" and returns the newly-created `Vector`.
-
-       ! Error Conditions
-
-         - If  an uncaught dataflow error is appended with `append`, the
-           dataflow error is propagated, and it is not added to the builder.
-
-         - If one or more uncaught dataflow errors are appended with
-           `append_vector_range`, the errors are *not* propagated.  All of the
-           values, including dataflow errors, are added to the builder.  To be
-           fixed in https://github.com/enso-org/enso/issues/9760.

-
-       ! TODO
-         We may want to revisit the fold pattern - it is required for correct
-         propagation of dataflow errors, but it is very easy to forget about it
-         and get wrong error propagation. Instead we may want to have a `Ref`
-         inside of the Builder. Any error detected during `append` could set
-         that `Ref` and then `to_vector` could propagate that error.
