Creates readers and writers that allow assignment to the attributes of the
singleton of the declaring object that correspond to the specified
symbols
.
# File lib/strelka/mixins.rb, line 297

symbols.each do |sym|
singleton_class.__send__( :attr_accessor, sym )
end
end
Creates instance variables and corresponding methods that return their
values for each of the specified symbols
in the singleton of
the declaring object (e.g., class instance variables and methods if
declared in a Class).

method named
newname
