Yes, but what I was thinking about specifically was mixing tcl and scheme code. Although given the large differences between the two languages, it is a better idea to just add special tcl procedures for evaluating scheme forms and make the tcl variable namespace completely separate from the scheme namespace. But this would miss part of the point of translators, I think. - Maciej Stachowiak
