That's a reasonably elegant extension, but it doesn't really solve the
problem any better than fixing the underlying parser problem.  A user who
can figure out how to pass a function with the appropriate name encoding,
which at this point nobody has figured out to do remotely, can more than
likely arrange for that function to be called, at which point it will be
parsed and any underlying parser bug exposed.
