about_function incorrect by PowerShellDon

From the doc about_functions:


     The following example is a function called Get-SmallFiles. This function
     has a $size parameter. The function displays all the files that are
     smaller than the value of the $size parameter, and it excludes
     directories:

         function Get-SmallFiles {
             param ($size)
             Get-ChildItem c:\ | where {$_.Length -lt $Size -and !$_.PSIsContainer}
         }


     In the function, you can use the $size variable, which is the name
     defined for the parameter.

     To use this function, type the following command:

         C:\PS> function Get-SmallFiles –Size 50


     You can also enter a value for a named parameter without the parameter
     name. For example, the following command gives the same result as a
     command that names the Size parameter:

         C:\PS> function Get-SmallFiles 50

Technically, you wouldn't use the keyword "function" when RUNNING the thing, right?
