How to return one and only one value from a PowerShell function?

Question

I\'ve learned from this Stack Overflow question, that PowerShell return semantics are different, let\'s say, from C#\'s return semantics. Quote from the aforementioned quest

You could replace echo (alias of Write-Output) with Write-Host:

PS> function test{ Write-Host "foo";"bar"} 
PS> $a = test                                    
test                                          
PS >$a                                         
bar
