 Test -and -or and -nest modifiers, assuming the following:
 
-  * Modifiers are respected in both hashrefs and arrayrefs (with the obvious limitation of one modifier type per hahsref)
-  * Each modifier affects only the immediate element following it
-  * In the case of -nestX simply wrap whatever the next element is in a pair of (), regardless of type
-  * In the case of -or/-and explicitly setting the logic within a following hashref or arrayref,
-    without imposing the logic on any sub-elements of the affected structure
-  * Ignore (maybe throw exception?) of the -or/-and modifier if the following element is missing,
-    or is of a type other than hash/arrayref
+  * Modifiers are respected in both hashrefs and arrayrefs (with the obvious
+    limitation of one modifier type per hahsref)
+  * When in condition context i.e. where => { -or => { a = 1 } }, each modifier
+    affects only the immediate element following it.
+  * When in column multi-condition context i.e.
+    where => { x => { '!=', [-and => [qw/1 2 3/]] } }, a modifier affects the
+    OUTER ARRAYREF if and only if it is the first element of said ARRAYREF
