###Aggregate-List

Examples:

Sum:

```powershell

1..10 | Aggregate-List { $input + $acc} -seed 10

#65

```

Product:

```powershell

1..10 | Aggregate-List { $acc * $input } -seed 1

```

String reverse:

```powershell

"abcdefg" -split '' | Aggregate-List { $input + $acc }

#gfedcba

```

###All-List

Examples:

```powershell

1..10 | All-List { $input -le 6 }

#False

```

###Any-List

Examples:

```powershell

1..10 | Any-List { $input -eq 5 }

#True

```

###Except-List

Examples:

```powershell

1..10 | Except-List 1,3,5,7

#2

#4

#6

#8

#9

#10

```

###First-List

Examples:

```powershell

1..10 | First-List { $input -eq 5 }

#5

1..10 | First-List { $input -eq 11 }

#Throws exception

```

###Intersect-List

Example:

```powershell

1..10 | Intersect-List $(5..15)

#5

#6

#7

#8

#9

#10

```

###Repeat-List

Example:

```powershell

1..3 | Repeat-List 2

#1

#1

#2

#2

#3

#3

```

###SelectMany-List

Example:

```powershell

"abc", "def" | SelectMany-List { $input.ToCharArray() }

#a

#b

#c

#d

#e

#f

```

###Single-List

Example:

```powershell

1..10 | Single-List { $input -eq 5 }

#5

1..10 | Single-List { $input -ge 5 }

#Throws exception

1..10 | Single-List { $input -eq 11 }

#Throws exception

```

###Skip-List

Example:

```powershell

1..10 | Skip-List 6

#7

#8

#9

#10

```

###SkipWhile-List

Example:

```powershell

1..10 | SkipWhile-List { $input -le 8 }

#9

#10

```

###Take-List

Example:

```powershell

1..10 | Take-List 3

#1

#2

#3

1..10 | Skip-List 3 | Take-List 3

#4

#5

#6

```

###TakeWhile-List

Example:

```powershell

1..10 | TakeWhile-List { $input -lt 4 }

#1

#2

#3

```

###Union-List

Example:

```powershell

"a", "b", "c" | Union-List "c", "d"

#a

#b

#c

#d

```

###Zip-List

Example:

```powershell

"a", "b", "c" | Zip-List $(1..4) { $first + $second }

#a1

#b2

#c3

"a", "b", "c" | Zip-List $(1..3) { $first * $second }

#a

#bb

#ccc

```
