Ah, now the lightbulb goes off.  I should have remembered the
convention of having the setter have an equals sign as part of the
name.  I'm too used to languages that determine which accessor is used
based on which side of the assignment it appears rather than actually
using a method name to syntactically simulate assignment.

Thanks for the help.
