generator->string generator #!optional kprocedure

Reads items from generator and returns a newly allocated string of them. It is an error if the items are not characters. By default, it reads until the generator is exhausted.

If an optional argument k is given, it must be a non-negative integer, and the string ends when either k items are consumed, or generator is exhausted; therefore generator can be infinite in this case.
