pltcl and modules question

Hi,

is there any way to use a module within a pltcl script, i.e. have
load /path/to/mystuff.so
or
package require mystuff
in a script.
The reason why I am asking: I have recently converted a fairly slow script
(lots of regex) into one compiled module that basically does all regex at once, and critcl
made it fairly easy to build a .so or a tcl package out of the code

Similarly, would it be possible to access loaded module from perl script, i.e. have
use mystuff;
line
