I actually usually do things like

        undef $/;
        $template = `cat template`;     #rude open
        $template =~ s/\[(\w+)\]/$UserVariables{$1}/g;

to avoid the security concerns.  /gee is correct for simple interpolation,
although how to match even curlies is a headache.  Someone has proposed
a regex primitive to match a syntactically correct statement, for use in such
cases -- is it an RFC?
