What "simple implementation in userland" do you have in mind? Can you =
provide an example?

json_decode() is not an acceptable substitute here -- as David Gebler =
has observed, decoding a large JSON structure can have a significant =
impact on memory usage, even if the data is immediately discarded. Any =
implementation based on string processing, on the other hand, is likely =
to be dramatically slower, and may have subtle differences in behavior =
from PHP's JSON parser.=
