Didn't know you could just print it :-)  I don't handle lightuserdata often..

If we are arguing over whether this function should exist upstream, I
don't think this point should count against it.  It's outside the
scope of simply viewing the contents of a userdata.  :>  Whether you
understand the risks of using those contents and take measures to
mitigate it -- that's up to you :>

I'm only arguing because it seems like you'd rather not see this
become part of Lua because of the risk of how it can be misused ..
