In addition to getting an item (as already noted):

{"hoo", get item 2 of L} as string --> "hooha"

...it's possible (taking Matt D's point about a reference) to coerce the contents of the list:

contents of {"hoo", item 2 of L} as string --> "hooha"

- but evidently not the contents of an individual item:

{"hoo", contents of item 2 of L} as string --> "hoo"

In cases like this, I sometimes go back to an earlier OS to compare behaviour. Turns out that the behaviour in OS 9.1 (AS 1.8.3) is actually the same - so we can't even claim lack of consistency here.

However, this still *seems* like a bug to me. According to the ASLG, a multi-item list can be coerced to a string - with just one qualification: "Only a list whose items can all be coerced to strings can be coerced to a string." On that basis, and since this works on the individual item:

item 2 of L as string --> "ha"

...I'd have expected coercion of the entire list to be successful, too - without the need to add explicit evaluations. (OK, so call me an optimist.)
