Would someone explain the syntax of nested blocs vis-a-vis the use of
Array.each ?

 I thought that 'lname' would be an element of an Array in the program
below.  But the interpreter (ruby-1.8.4-1.fc3 in Fedora Core 3)  tells
me it is the entire Array.

 first_name = Array.[]( "Joe ","Albert ","Lilly ","Henry ","Becky
","Ray ")
 last_name = Array.[]( "Groster", "Riplaid", "Pewley", "Lundrund",
"Banks" }}

tmp_name = "long string of nothing"

first_name.each { |fname|

     last_name.each { |lname|

          tmp_name = fname
         #  tmp_name = fname + lname   # This produces a syntax error
         #  puts(tmp_name)

         puts( lname.inspect)

    }   

}
