#        a = "hello there"
#        a[1]                   #=> 101
#        a[1,3]                 #=> "ell"
#        a[1..3]                #=> "ell"
#        a[-3,2]                #=> "er"
#        a[-4..-2]              #=> "her"
#        a[12..-1]              #=> nil
#        a[-2..-4]              #=> ""
#        a[/[aeiou](.)\1/]      #=> "ell"
#        a[/[aeiou](.)\1/, 0]   #=> "ell"
#        a[/[aeiou](.)\1/, 1]   #=> "l"
#        a[/[aeiou](.)\1/, 2]   #=> nil
#        a["lo"]                #=> "lo"
#        a["bye"]               #=> nil
#


From this, i think a[1] is the odd one out.
I'd prefer a[1] #=> "e"
