The exact details of why this I'm not familiar w/ but it is a scope
issue.  The require won't make the local variable into global for you.

The 'myhash' isn't global just because it is declared outside of other
things.. prefix that myhash w/ a $ and make it a global.

$myhash =  { "a" => "ay", "b" => "bee", "c" => "sea" }

-----------

puts $myhash['a']
