Scheme Procedure: SRV:send-reply . fragments

Output the fragments to the current output port.

The fragments are a list of strings, characters, numbers, thunks, #f, #t – and other fragments. The function traverses the tree depth-first, writes out strings and characters, executes thunks, and ignores #f and '(). The function returns #t if anything was written at all; otherwise the result is #f If #t occurs among the fragments, it is not written out but causes the result of SRV:send-reply to be #t.
