not using [parameter()] on some parameters in a PowerShell advanced function

If you are doing advanced functions and have the parameters decorated [parameter()], would there be any reason to NOT decorate a parameter with [Parameter()] . I've seen this a few times and don't k开发者_Python百科now whether its just a case of laziness, oversight, or purposeful design.

Laziness I think but to be fair, it isn't needed if you aren't using any special parameter attibutes like Mandatory, Position, etc. As long is one parameter is marked [Parameter(...)] or the param block is marked [CmdletBinding(...)] PowerShell will interpret that function as an advanced function. OTOH there is no harm in adding the empty [Parameter()] to parameters.
