Get-Alias ?

If you want to find the cmdlet "behind" the alias ?, command Get-Alias ? won't help you, because ? will be treated as a wildcard for a single character, and you will get all single-character aliases:

PS>get-alias ?

CommandType Name Definition
----------- -        ---       ----------
Alias                 %        ForEach-Object
Alias                 ?        Where-Object
Alias                 h       Get-History
Alias                 r        Invoke-History

To use ? as the literal value, you have to escape it with a backtick and put it in single quotes:

PS>get-alias '`?'

CommandType Name Definition
-----------           ----    ----------
Alias                  ?       Where-Object

Double quotes don't work in both V1 and V2 CTP3. Does somebody know why?
