h3. Extensions to +Symbol+
h4. +to_proc+
The method +to_proc+ turns a symbol into a Proc object so that for example
<ruby>
emails = users.map {|u| u.email}
</ruby>
can be written as
<ruby>
emails = users.map(&:email)
</ruby>
TIP: If the method that receives the Proc yields more than one value to it the rest are considered to be arguments of the method call.
Symbols from Ruby 1.8.7 on respond to +to_proc+, and Active Support defines it for previous versions.
