Question

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

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) 

Actually the goal is to write such code:

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

Answer 1

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 !
