How to use Powershell Where-Object like an IN statement

I have the following code which works:

foreach ($db in $svr.Databases | 
         where-object {
         $_.name -eq "testDB" 
         -or $_.name -eq "master"
         -or $_.name -eq "model"
         -or $_.name -eq "msdb" } )
{
  write-output $db.name
}

Is a cleaner way to do this?

Something like:

foreach ($db in $svr.Databases | 
         where-object {$_.name -in "testDB, master, model, msdb" } )    
{
  write-output $db.name
}
