In a previous tip, we showed you how adding a single comma can change the way functions return arrays. With this trick, you can force a PowerShell function to return an array in one chunk. Have a look:
function test { (1..10) } Test | ForEach-Object { "Receiving $_" }
Arrays returned by functions are by default unwrapped and processed as single values. With a simple comma, this will change:
function test { ,(1..10) } Test | ForEach-Object { "Receiving $_" }
