That would be fine too.  But, if you'd do #2 (object assignment
method), to be consistent, you'd call the method "()=".  I kind
of like simply "=" (and "+=", "-=", etc).  But, I don't care
about it too much.

BTW, the you'd probably do this in Class instead (to handle it
for all classes):

class Class
alias :[] new # works now
alias :() new # your proposed null method name
alias :@  new # my proposed null method name (like -@ and +@)
end
