add reduce operator

hello Guys !

the idea to add another structure to simplify code execution for example:

# is the same  1+2+3+4+5+6+7+8+9+10
PS  > :[+] 1..10
55

# use all arithmetic operator and possibility to store in variable
PS > $result = :[-] 10,32,54
PS > $result

# possibility to add personal reduce filter
PS > filter MyPersonalFilterToListAllWordBeginningByLetterh {
          if($_.tostring().StartsWith('h')) {
                $_
        }
    } 
PS> :[:MyPersonalFilterToListAllWordBeginningByLetterh] @( 'hello','lol','test','fooooo' )
hello

I think this has already been discussed in https://github.com/PowerShell/PowerShell/issues/8098 too. See that issue for some definitions of functions that work like the proposed operator.

We already have questions to add support for LINQ and extension methods which is more promising.
