I find lambda quite useful for creating simple anonymous functions to pass
to GUIs as button commands and the like.  I suppose the same effect could be
obtained by adding a couple more lines to define a temporarily-named
function, but then I'd have to think up a name.  I've been known to waste
hours trying to come up with names for new computers. I'm not quite so
indecisive about functions, but it does seem to be one of my weak points.
