These are actually exactly the same method in CGI::FormBuilder, which  
says:

*param  = \&field;
*params = \&field;
*fields = \&field;
sub field {

The source for CGI::FormBuilder says that field, if called without an  
argument, will return "an array of the names in list context, and a  
hashref of name/value pairs in a scalar context".  This is problematic  
behavior with TT, as TT always uses a list context, so form.fields and  
form.field are both going to return an array of field names.

Looking at the source though, it looks like you should be able to get  
at them this way:

[% form.field( 'firstname' ).label %]
