Untrusted PL/Tcl?

Hi all,

there have been a couple of questions WRT doing untrustable
things like file access, LDAP and the like from inside of
triggers or functions.

Tcl is a powerful language and could do all that, but the
interpreter used in PL/Tcl is a safe one, because it is a
trusted procedural language (any non-superuser can create
functions). I think it should be pretty easy to build a
second PL handler into the module, that executes the
procedures in a full featured Tcl interpreter, that has all
capabilities. This one would be installed as an untrusted PL,
so only DB superusers could create functions in that
language.

Should I go for it and if so, how should this language be
named?
