Raise an error when constructing a Series or DataFrame with mixed types (e.g. string + number)

I think this is a very similar issue to this: https://github.com/pola-rs/polars/issues/11009. We really should do a pass on the Python -> Polars parsing to make it more restrictive by default,...

I would be in favour of extending `Series.reinterpret`/`Expr.reinterpret` to support an arbitrary `dtype` argument. The only requirement being that the size of the two types is the same (e.g. no...

Extend `Expr.reinterpret` to arbitrary primitive numeric types

I took the liberty of editing your title.

Inconsistent `1 // 0` behavior between Expr/Series and DataFrame

I'll take care of this tomorrow, ensuring we give a proper error.

feat(python): allow df.rename and lf.rename to take a renaming function
