[alexeypetrushin]

Thanks, but seems like it's not compiling..., do I miss something?
    
    
    import strformat, sugar
    
    proc map_csv[T](
      csv_file_path: string,
      map: (
        row: (key: string) -> string
      ) -> T
    ): seq[T] =
      for i in 1..3:
        result.add map(proc (key: string): string = fmt"{key} {i}")
      result
    
    
    proc load_companies2(): seq[string] =
      map_csv("companies.csv", (row) => block:
        let v = row("symbol")
        v
      )
    
    
    Run
