13 | Test -and -or and -nest modifiers, assuming the following: |
e5360be4 |
14 | |
6c8ac65d |
15 | * Modifiers are respected in both hashrefs and arrayrefs (with the obvious |
16 | limitation of one modifier type per hahsref) |
17 | * When in condition context i.e. where => { -or { a = 1 } }, each modifier |
18 | affects only the immediate element following it. |
19 | * When in column multi-condition context i.e. |
20 | where => { x => { '!=', [-and, [qw/1 2 3/]] } }, a modifier affects the |
21 | OUTER ARRAYREF if and only if it is the first element of said ARRAYREF |
