I think he's talking about the 'arguments' scope in particular, as it
has weird quirks that aren't exhibited by any other CF scopes (i.e.
the ability to dereference like an array). StructKeyExists is still
the proper way to test for an optional argument; in that sense
treating arguments like a struct is the proper thing to do. Just
don't necessarily expect it to ALWAYS behave exactly like a "real"
struct.
