[PD] tcl inside of PD

[august]

hej list,

two questions.

1.) since pd is based on tcl/tk, would it be possible (easy?) to impliment
the tcl scripting language inside of PD?

2.) when externals and/or libraries are included in the pd path (say in
the .pdrc file) are they loaded into entirely into memory or just
registered somehow?  I have the feeling that librarys are loaded, but
externals are not.

rolling along - august.
