Bryce Kampjes bryce@kampjes.demon.co.uk is claimed by the authorities to have written:
You might want to try using blocks e.g.: connectionPooler withConnection: [:conn| the code that uses the connection "conn"].
This way the method withConnection: can both open the connection and close it. This is a fairly standard idiom to wrap creation and deletion of a resource.
Don't forget #ensure: as in [file _ filename openfile. things doStuff] ensure: [file close] which will close the file even if the code in the receiver block does a non-local return.
