Sets @scheme[port]'s display handler (via
|
|
@scheme[port-display-handler]) so that when it encounters these
|
|
values:
|
|
|
|
@itemize[
|

@item{exact, real, non-integral numbers}
|
|
|

@item{syntax objects}

|
it uses @scheme[write-special] to send snips to the port,
|
|
instead of those values. Otherwise, it behaves like the
|
|
default handler.
|
|
|
|
To show values embedded in lists and other compound object, it uses
|
|
@scheme[pretty-print].}
