In Java, symbols are there under the covers, in the form of interned strings.
The trouble is that there is no way to examine a string to see if it is
interned, so people engage in a lot of String.equals where == would suffice.

Is a chair finely made tragic or comic? Is the          John Cowan
portrait of Mona Lisa good if I desire to see           cowan at ccil.org
it? Is the bust of Sir Philip Crampton lyrical,         http://ccil.org/~cowan
epical or dramatic?  If a man hacking in fury
at a block of wood make there an image of a cow,
is that image a work of art? If not, why not?               --Stephen Dedalus
