Every traditional HTML form submission creates a record of the values of
all widgets from this form. Even if the form has no widgets, you still
get a record: the trivial empty record (or "unit" value). The 'action'
attribute of <submit> takes a function from the appropriate record
type. Thus, in your example with a no-widgets form, it is necessary to
pass a function over the unit type, to stand for the empty widget-values
data.

delete id ()
The second argument seemed unnecessary, so I tried removing it.
However, removing the second argument gave a compile error:
