All this discussion about arithmetic ifs has goaded me into posting my own
particular pet construct.

Since I do a lot of programming that involves mathematical expressions of one
sort of another I often find myself wishing for an if construct that looks
like

	if ( foo < bar < baz )
	  do_something();
	else
	  do_something_else();

which is, of course, equivalent to

	if ( ( foo < bar ) && ( bar < baz ) )
	  do_something();
	else
	  do_something_else();

Is there any reason why such a construction is not practical?  If not, why has
no language (that I am aware of or can program in) implemented such a
construction?  Good idea or bad idea?
