Silly question re: bind_param vs: bind_columns

[jadams01]

I'm looking at DBI 1.14 and wondering why isn't there a bind_params method like:

$rc = $sth->bind_params(@refs_to_params); #dies if wrong number of params

or

$rc = $sth->bind_params(%hash_of_params_with_field_names_or_numbers); #dies if hash 
key mismatch

It seems like an obvious idea, so I assume there's a good reason it hasn't been 
implemented.
