# XXX: the coercions here are due to the provider promiscuously updating the properties on the

# <lecture>
# THIS is why updating the new_resource in a provider is so terrible, and is equivalent to methods scribbling over
# its own arguments as unintended side-effects (and why functional languages that don't allow modifcations
# of variables eliminate entire classes of bugs).
