The error message here will be misleading if it's a 3 arg block,
saying that it wants 3 args, but was given 0, when in fact you *offered*
two args.
Perhaps the tests could be done in the reverse order:
numargs = 0 ifTrue: [^self value].
numargs = 1 ifTrue: [^self value: argument1].
^self value: argument1 value: argument2.
Then, you'll get a sensible message... "offered 2, wanted 3"
