Subject: Re: Finding if an array contains a data type

Several ways to test, but probably I'd like best

x=["a","b",2, "c"]
puts "This array contains numbers" if x.find{|t| t.kind_of?(Numeric)}

The method find is given to class Array by Enumerable, not so obvious.
Not knowing find nor kind_of?, I'd probably do


x=["a","b",2, "c"]
x.each { |t|
  if t.to_s =~ /^\d+(\.\d+)?$/ then
    puts "This array contains numbers"
    break
  end
}

But that's just ugly.
