# What’s planned? (the big stuff)

- ## $h->{FetchHashReuse} = 1; or … = {};

  - Enables greatly optimized fetchrow_hashref() performance
  - if you promise to play by the rules!

- ## $sql_new = $dbh->preparse($sql_orig, $return, $accept)

  - Gateway to extra functionality in the future, especially portability
    - rewrite comments to suit database
    - rewrite placeholders e.g. ‘?’ -> ‘%s’
    - rewrite ODBC escape sequences
    - (thanks to Scott Hildreth for kick-starting this work)

- ## Definition of array binding API (e.g. for bulk loading)

  - (thanks to Dean Arnold for doing much of this work)
