Get-Member on empty collections

PowerShell's pipeline just loves to unravel collections, with the result that sometimes, when you want to do something on the collection itself, you can't. Like with Get-Member:

$blah.Catalogs | Get-Member
Get-Member : No object has been specified to the get-member cmdlet.

What happened? Did $object.Catalogs return null, or did it return an empty IEnumerable? This has bitten me a few times, especially when poking around in an API for the first time (ie: at this point I have no idea what 'Catalogs' is, whether it's ICollection or whatever).

The answer, I realize, is to avoid the pipeline:

Get-Member -inputObject:$blah.Catalogs

   TypeName: BlahNamespace.BlahCollection

Name           MemberType            Definition                                                      
----           ----------            ----------                                                      
Add            Method                System.Void Add(Microsoft.SqlServer.Management.IntegrationSer...
Clear          Method                System.Void Clear()                                             

Much better
