Is it desirable though?
I mean if we ever decide to switch from dejagnu to something else,
adding parsing of our dg-* grammar is not that hard, and while we rely
on some tcl details already (e.g. the {}s vs. ""s for regular expressions
etc.), allowing arbitrary embedded tcl will make that effort even harder.
