We would like to learn about your use case. For example, if this feature is needed to adopt Narwhals in an open source project, could you please enter the link to it below?

Polars 1.0 is about to come out, and it will have collect_schema. We should add it here too

Please describe the purpose of the new feature or describe the problem to solve.
