Er, why would you want to store an array of hashes like that, instead of
just a hash?  It would make iterating much easier to use a hash like so:

log = {
  'where' => '/path/to/fileA',
  'when' => '/path/to/fileB',
  'bank' => '/path/to/fileN'
}

#repeat w/ 'top'

build = [log, top]

Then, "build[0]['where'] = '/path/to/fileA'".

Note that, in your implementation, the first array only contains the
strings "log " and "top", and not the hashes, so my last line would
evaluate to nil, not the path.
