Enhancement Description

Polars is blazing fast if all operations are collected into a single lazy query. Pandas doesn't get this speed increase and it was simpler to write commands as returning a new dataframe, even if this was slow.

Pseudo Code Implementation

instead of emitting code like

def clean(df):
    df = df.with_columns(OP_A)
    df = df.with_columns(OP_B)
    df = df.with_columns(OP_C)
   return df

emit code like this

def clean(df):
    return df.with_columns(OP_A, OP_B, OP_C)
