For a grails application, I need to find a list of objects whose "attr" is one in a dynamic list of strings. The actual HQL query is more complex, but the bit I need help with is this:

```
def result = MyObject.executeQuery("select o from MyObject as o where o.attr in :list",
    [list: aListOfStrings])

```

This is obviously not the right syntax, Grails throws it back at me as an "unexpected token", being the `:list` parameter.

Is this possible in HQL? I don't particularly want to use Criteria in this part of the codebase.
