I've written a one-liner that munges the contents of the clipboard using the PSCX cmdlets get-clipboard and out-clipboard. I needed to replace each block of whitespace with a comma. How could I eliminate the temporary variable $a?

$a = get-clipboard; $a -replace '\s+', ',' | out-clipboard 

Thanks.

No problem, just add parentheses. (get-clipboard) -replace "foo" | out-clipboard

Otherwise, the parser will try to pass -replace to get-clipboard as a parameter.
