In an interview Jeffrey Snover was asked:
“Seeing the way PowerShell has evolved, what is your biggest regret?”
He answered:
“The return keyword was a misstep. Because any command output prior to return is also included, it doesn’t behave intuitively.

In other programming languages returns a function only what’s specified with the key word “return”. In Powershell a function returns everthing what’s left in the “output channel”.
function Return-everything {
‘Simple string’
‘Another simple string’
Return 'Return should only return what comes after the key word return, right?'
}
This function in other languages would only return the content of the last line. Try it!
