I don't know if this issue existed previously
This is a documentation suggestion. The pages in this example are "about_Arrays" (http://technet.microsoft.com/en-us/library/hh847882) and "Even More Things You Can Do With Arrays" (http://technet.microsoft.com/en-us/library/ee692797.aspx)
Even though examples are given in VBs, no equivalent PS example is given, despite the ability to do so in PS.
