Description

Is pretty cryptic output for 'no value was passed':

proto_bin.c:135 E> problem while parsing package 'SET' with opaque 8126464
proto_bin.c:136 E> erroneous 'val' section
memcached.c:115 E> Server error 20: Invalid arguments
proto_bin.c:1102 E> memcached error 20: Invalid arguments

Contributor guide

Research direction
Examine the error logging in proto bin.c and memcached.c to identify the source of cryptic messages (e.g., lines 135-136 and 115, 1102) and trace the code path for missing value errors. Then propose and implement clearer error messages that describe the actual problem (e.g., 'no value provided for key').
