Subject: analyzer: Check that all iterators use ary operators.
X-Git-Tag: sysdb-0.8.0~141
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1c6d22596a811f02f04980e4a07fee5b1e899525;p=sysdb.git

analyzer: Check that all iterators use ary operators.

All iterators are based on a comparison <iter> <op> <expr> and the same
restrictions apply to all of them.
