AFAIK no.

Remember, a big part of the 'package' command, the search for packages, is
implemented in Tcl and plugged into the main command via 'package unkown'.
The relevant pieces of the core are in 'init.tcl', which sets up the
plugging, 'package.tcl' handling the general package mechanism, and 'tm.tcl'
for the Tcl Modules.

I haven't looked into the safe base for quite some time, last three years
back, I think, so I do not really know how feasible a hack is.

You are not in the 'package' command per se I think.

The search mechanism might be set up differently, see above about 'package
unknown' and the various files, and I think the safe base introduces some
sort of virtual paths which get translated by the aliases in the master into
the proper path names. I my dim recollection of its internals is right.

>  Quite logical, since it relates to the new tcl module TM system.
