of unordered values with no duplicates. It is a hybrid of Array's
intuitive inter-operation facilities and Hash's fast lookup.;To;;[I"KThe method <code>to_set</code> is added to Enumerable for convenience.;To;;[I"�Set implements a collection of unordered values with no duplicates.
This is a hybrid of Array's intuitive inter-operation facilities and
Hash's fast lookup.;To;;[I"Set is easy to use with Enumerable objects (implementing <code>each</code>).
Most of the initializer methods and binary operators accept generic
Enumerable objects besides sets and arrays. An Enumerable object
can be converted to Set using the <code>to_set</code> method.;To;;[I"ESet uses Hash as storage, so you must note the following points:;To:RDoc::Markup::List:
@type:BULLET:@items[o:RDoc::Markup::ListItem:@label0;[o;;[I"�Equality of elements is determined according to Object#eql? and
 Object#hash. Use Set#compare_by_identity to make a set compare
 its elements by their identity.;To;;0;[o;;[I"�Set assumes that the identity of each element does not change
 while it is stored. Modifying an element of a set will render the
 set to an unreliable state.;To;;0;[o;;[I"{When a string is to be stored, a frozen copy of the string is
 stored instead unless the original string is already frozen.;TS:RDoc::Markup::Heading:

shorthand for the {proper_,}{subset?,superset?} methods. The <code><=></code>
operator reflects this order, or return <code>nil</code> for sets that both
have distinct elements (<code>{x, y}</code> vs. <code>{x, z}</code> for example).;TS;;i;I"Example;To:RDoc::Markup::Verbatim;[I"�require 'set'
