I wonder if the new namespaces functionality will break compatibility for users. I guess I always assumed gawk was feature-complete, or at least a mature enough tool that I wouldn't expect compatibility breaks. 11. Namespaces have been implemented! See the manual. One consequence of this is that files included with -i, read with -f, and command line program segments must all be self-contained syntactic units. E.g., you can no longer do something like this: gawk -e 'BEGIN {' -e 'print "hello" }'
