A word of caution
I took me some time to figure out why my rake task wouldn't accept multiple parameters. All I got was the following error:

This, off course, has nothing to do with the new syntax as I thought but the space between my arguments on the command line.
Standard UNIX stuff, I know, but still… sneaky.
