hvanhovell opened a new pull request, #49038: URL: https://github.com/apache/spark/pull/49038
### What changes were proposed in this pull request? We added a couple of helper functions that make it easier to work Columns in the Classic API. This covers functionality that creates a Column from an Expression, and creating (named) Expressions from a Column. There are currently multiple ways of doing the same thing and this is confusing. This PR attempts to simplify this a bit, by making the following changes: - `ExpressionUtils` is moved to the background. `ClassicConversions`/`ColumnConversion` are now predominantly used. The benefit of this is that most code now looks like pre-Spark 4 code. - `ExpressionUtils.expression(..)` and `ExpressionUtils.column(..)` are not implicit anymore. This was confusing. - `testImplicits` now supports both Expression -> Column and Column -> Expression conversions. ### Why are the changes needed? Easier to understand code. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
