> {{F.regexp_replace}} in PySpark currently only supports strings for the
> second and third argument:
> [https://github.com/apache/spark/blob/1df6006ea977ae3b8c53fe33630e277e8c1bc49c/python/pyspark/sql/functions.py#L3265]
> In Scala, columns are also supported:
> [https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L2836|https://github.com/apache/spark/blob/1df6006ea977ae3b8c53fe33630e277e8c1bc49c/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L2836]
> The desire to use columns as arguments for the function has been raised
> previously on StackExchange:
> [https://stackoverflow.com/questions/64613761/in-pyspark-using-regexp-replace-how-to-replace-a-group-with-value-from-another|https://stackoverflow.com/questions/64613761/in-pyspark-using-regexp-replace-how-to-replace-a-group-with-value-from-another,],
> where the suggested fix was to use {{{}F.expr{}}}.
> It should be relatively straightforward to support in PySpark the two
> function signatures supported in Scala.
