And the highly esoteric version...

n = [[]]
s = [[]]
'abcd1234abc123'.each_byte { | x |
  if (47..57).include?(x)
    then s << []; n.last << x
    else n << []; s.last << x
  end
}
n = n.reject { | x | x.empty? }.map { | x |
  x.map {| y | y.chr }.join("").to_i }
s = s.reject { | x | x.empty? }.map { | x |
  x.map { | y | y.chr }.join("") }
result = if n.length > s.length
  then n.zip(s).flatten.compact
  else s.zip(n).flatten.compact
end
p result # => ["abcd", 1234, "abc", 123]
