we would have loved to do this, except that it would have turned

	if {test -s errors} {
		openfile errors
	} {
		rm -f errors
	}

into

	if @{test -s errors} @{
		openfile errors
	} @{
		rm -f errors
	}

which we considered worse than the alternative, which is the
explicit ``value of'' operator.

[i assume you mean, in es terminology, ``code fragments'' not
``code segements.'']
