Could you give an example of how you think it should work?  (Just
curious and trying to keep up.)

Are you thinking that this should match:

  [[ "string" =~ [a-z] ]] && echo matched || echo not matched

Which this should not match?

  [[ "string" =~ "[a-z]" ]] && echo matched || echo not matched

Thanks
