• File foreach-withexception.ps1 — part of check-in [8861eb2d12] at 2018-06-10 14:25:29 on branch trunk — simple function like foreach, but that traps exceptions using v2, and logs then in the $lastex variable. this way the pipeline can continue and process the objects that aren’t having errors happen against them. eventually this needs to be made much better, and be a v2 advanced function (user: karl prosser size: 1217)
