I know these rules well. Template logic is as dumb as possible. If a
field is present in hash (even if it has a value undef) -> show input
field, if it is absent -> doesn't show field. Not ??
I even think about 'keys' method for determining, but it is too
complex for such simple problem.

It is just another variable. I think it is needless to pass second
variable for displaying that first variable has a value - undef. We
can remove method 'defined' and use such techique for determining
value 0, for example :)
I think that Larry Wall implements 'exists' function not without
reason...
