! defined @$token

A string is being returned from the lexer, and since it's not a reference, trying to dereference it is an error. Maybe you want:

 ! ref($token)

But then the lexer is still returning too many TEXT tokens (line 2 and 3 of the output in the OP), so something else needs to be fixed. (update: and I think the fixing needs to be done in HOP::Lexer)(update2: nope, it was the TEXT regex that needed to be fixed)
