How to pass arguments to function referenced by variable

Question 1

I have a function ‘foo’ and a variable ‘$foo’ referencing it.

function foo
{
    param($value)
    $value + 5
}

$foo = foo
$foo

1

2

3

4

5

6

7

8

9

function foo

{

param($value)

$value + 5

}

$foo = foo

$foo

I can call $foo without args, but how can I pass parameters? This does not work:

$foo 5
$foo(5)

1

2

3

$foo 5

$foo(5)

Actually the goal is to write such code:

function bar {
  param($callback)
  $callback 5
}

bar(foo)

1

2

3

4

5

6

7

function bar {

param($callback)

$callback 5

}

bar(foo)

Question 2

The problem is when you do

$foo = foo

You put the result of the function in the variable $foo, not the function itself !

Try this :

$foo = get-content Function:\foo

And call it like this

& $foo 5

Hope it helps !
