let ctx = SessionContext::new();
let df = ctx.read_csv("tests/data/regex.csv", CsvReadOptions::new()).await?;

// use the regexp_like function to test col 'values',
// against patterns in col 'patterns' without flags
let df = df.with_column(
    "a",
    regexp_like(vec![col("values"), col("patterns")])
)?;
// use the regexp_like function to test col 'values',

let df = df.with_column(

)?;
// literals can be used as well with dataframe calls
let df = df.with_column(
