I prefer Guido's earlier suggestion of {/} for the empty set (assuming no
parsing ambiguities?):
a) requiring 'set()' for empty sets is inconsistent with (), [], {} for
empty collections of other kinds
b) {/} kind of looks like phi (circle with a slash through it, to quote
my engineering students ;-), which some of the books on my shelves use
for empty set.
