If you'll allow me to counter-channel:

Christian hates giving this special syntax form access to local/global
variables, since it's a security risk that's not apparent unless you
know what you're looking for.  He prefers to use allvars() to achieve
the same end, since it's explicit.

He's not opposed to variable access in general.  Write-only variables
don't tend to find much use.
