[Python] creating cols from cols that are being created within the same `with_columns` method

Here col "AB" is just being create and at the same time is being used as input to create col "ABC". This fails.

(pl.col("A")+pl.col("B")).alias("AB"),
(pl.col("AB")+pl.col("C")).alias("ABC")
)


Or the only way to do this is just using a second with_columns method.

df1 = df.with_columns(
(pl.col("A")+pl.col("B")).alias("AB")
)
df2 = df1.with_columns(
(pl.col("AB")+pl.col("C")).alias("ABC")
)
