relating %s to $t is extra work.

or
echo 'the problem is ', $t;
be sure I can do it in code. In Tcl, interactive session:
strobel@s114-intel:~> tclsh
% set t " - solved - "
- solved -
% set msg {the problem is $t}
the problem is $t
% puts $msg
the problem is $t
% puts [subst $msg]
the problem is - solved -
%
/Str.
