The approach you're suggesting seems very ugly :-)
I'd suggest trying one of two different approaches :
* Create a definition to which you'll pass an array of all instances,
which will then call the redminde::instance for each. This only
works of course if you're not trying to add new instances from
various puppet classes/definitions.
* Create a fact which returns all of the redmine instances of the
puppet client. This has quite a few limitations, but might work
depending on what you need exactly.
