Fixed missing'[' in POD example

[pdl]

Just a tiny typo.

Hi! Actually your proposed change wasn't correct, as
[ -and => { col => { -like => 'foo%' } }, { col => { -like => '%bar' } } ]
!=
[ -and => [ { col => { -like => 'foo%' } }, { col => { -like => '%bar' } } ] ]

I cleaned up the examples nevertheless (as they did contain syntax errors) and committed the result as a948b1f

Thank you for the report!
