You might be right - I have no knowledge of the complexities of the parse order - but I would have thought that the comma would not be unexpected because of the @ sigil. Surely, knowing that the clause inside the curley braces is in list context it would be expecting a list, a comma shouldn't come as any surprise.
The error message reports three bare words, so it knows what the comma is and it recognises them as a list, it seems though it ignores the sigil and the braces.
