=head2 yesno
Provides an easy "Yes/No" widget. C<No> returns a value of blank/false,
and C<Yes> returns 1/true.
Calling:
{
name => 'varname' || undef, ## Derived from item if called by
# [PREFIX-options] or [PREFIX-accessories]
type => 'yesno' || 'yesno radio', ## Second is shorthand for variant=>radio
variant => 'radio' || 'select', ## Default is select
}
The data array passed by C<passed> is never used, it is overwritten
with the equivalent of '=No,1=Yes'. C<No> and C<Yes> are generated from
the locale, so if you want a translated version set those keys in the locale.
If you want another behavior the same widget can be constructed with:
[display passed="=My no,0=My yes" type=select ...]
