This check happens when "read" returns 0, aka the whole input
is empty, so it doesn't affect the case of some date.

Put ")quit" aside, the bug I'm talking about is when input
is empty, currently:
(1) -> ^D
Cannot find a definition or applicable library operation named 1
with argument type(s)
Variable(->)
Perhaps you should use "@" to indicate the required return type,
or "$" to specify which version of the function you need.
It seems when you issue "CTRL-D", the system receives "(1) ->".

Since the architectural change will not happen soon, I suggest
to replace
swrite(sock, ")quit", 5, "quitting");
with a simple
return;
