Running function of variable name [duplicate]

Question

I expected this code to run Foo():

function Foo {
    [Console]::WriteLine("Foo")
}
$Bar = [Console]::ReadLine()
# If $Bar is Foo then it should do the function "Foo", right?

$Bar()

Functions in powershell follow a verb-noun pattern and most .NET methods have a powershell equivalent known ascmdlet so your function can be :

function Get-Foo {
    #[Console]::WriteLine('Foo')
    Write-Host 'This is foo'
}

Get-Foo

or

$Bar = Get-Foo

$Bar

Get-Command and Get-Help are your friends, try them out.

Doesn't exactly do what I want it to, I think that's my fault for making it too broad, I fixed it to be what I actually want to do.

you feed $bar with user input from [console]::readline() which will always be a string.... foo function` and foo string are not the same thing
