(pardon me for butting in)

I don't believe there's much, if anything, in the TASH.* hierarchy that
isn't supported either by Ada2005 (Arrays, Lists, Strings) or by GNAT
extensions (File, Regexp, Platform, System).

For those with only a passing interest -- these Tcl features were made
private at Tcl 8.5, so it was no longer possible to provide a binding to
them.

Come to that, there's an awful lot of the Tcl binding in TASH that you
really won't need! Write the GUI in Tcl/Tk and provide the minimum
additional commands (exporting of Ada application interfaces to the Tcl
domain) for your needs.

One thing I never got round to doing is working out how to tell the Tcl
side that a variable had changed so as to avoid polling. I have a
feeling this is possible, but I didn't _have_ to do it. Perhaps use
Tcl_SetVar & trace??? (but there will probably be threading issues).
