well, many places parse '@' left to right, e.g.
chan_alsa.c, chan_oss.c in the "dial foo" command
pbx.c in function handle_show_dialplan
apps/app_voicemail.c in all places where it is looking for a 'context'
channels/chan_iax2.c in iax2_transfer()
channels/chan_local.c in local_alloc()
channels/chan_sip.c
pbx/pbx_config.c

and a few others. In all these cases, i would expect that
a "context" in which to interpret the string as the last
thing to appear in the string itself.
