Function like text() but with auto placement like legend?

Does such a function exist which simply addes some text to a plot, without having specify the x/y location, and without also adding a line/marker graphic?
In other words, I am looking for a function which has output like text() (i.e., no other graphics, like legend() has), but which has the ability to intelligently place the text object, as in legend(), i.e.
legend(____,'Location',_____)

OTOH, as noted in the Answer below, I can think of a multitude of instances wherein I would like text to be located "without being touched by human hands". :)
That's certainly one "intelligent", locating paradigm, yes...as noted, the one example I can think of presently in Matlab is legend with the 'best' location property value. It isn't always perfect, but is, on the whole in my experience, better than a random choice of a fixed location when one isn't positive a priori what the shape of the plotted data is.

No, altho I can guess the desire...would be kind of a nice touch if Matlab could/would automagically locate a desirable place to place a label for a line label, etc., without having to compute it. It's sometimes difficult to know programmatically where to place it so doesn't obstruct the already existing information on the axes.
Only thing I can think of at the moment is there are the 'best'|'bestoutside' values for the 'Location' property in legend but I don't think there are any other user functions with similar abilities. Some of the CurveFitting tools may label stuff, I'm not sure??? but those are applications, not user functions.
What the hey, submit an enhancement request...
PS. I didn't search but there's always a possibility somebody else has had the similar yen and has written/uploaded a solution on File Exchange.

In the case where you need only a single such item per axes:
h = line(nan, nan, 'Color', 'none');
legend(h, 'Your Message Here', 'Location', ....)

How to remove the space used to the plotted item symbol (in this case none, blank) on the left?

You would have to use two or more outputs for legend(), and access the graphic objects such as the text() object and adjust its Position property.
Note that two or more outputs for legend() is now undocumented and unsupported, and could be removed Any Release Now.

I suppose the somebody who wrote this one thought it better than whatever was original...

There is a function in the Matlab File Exchange that addresses this issue.
