thing?
(name thing-name (default \"chbouib\"))
(port thing-port
(default (current-output-port)) (thunked))
(loc thing-location (innate) (default (current-source-location))))
This example defines a macro 'thing' that can be used to instantiate records
of this type:
(thing
(name \"foo\")
(port (current-error-port)))
The value of 'name' or 'port' could as well be omitted, in which case the
default value specified in the 'define-record-type*' form is used:
(thing)
The 'port' field is \"thunked\", meaning that calls like '(thing-port x)' will
actually compute the field's value in the current dynamic extent, which is
useful when referring to fluids in a field's value.
A field can also be marked as \"delayed\" instead of \"thunked\", in which
case its value is effectively wrapped in a (delay …) form.
It is possible to copy an object 'x' created with 'thing' like this:
(thing (inherit x) (name \"bar\"))
This expression returns a new object equal to 'x' except for its 'name'
field and its 'loc' field---the latter is marked as \"innate\", so it is not
inherited."
