Powershell: Read-Host result doesn't work with hashtable lookup

[vors]

Steps to reproduce

PS C:\dev\PowerShell> $response = Read-Host 'foo'
foo: 2
PS C:\dev\PowerShell> $response
2
PS C:\dev\PowerShell> $response -eq 2
True
PS C:\dev\PowerShell> $h = @{2 = @('A')}
PS C:\dev\PowerShell> $h[$response]    # BUG!!
PS C:\dev\PowerShell> $h[2]
A
PS C:\dev\PowerShell>

Expected behavior

$h[$response] should be A

Actual behavior

$h[$response] is $null

I believe that this is because the 2 is being seen type converted to an int as opposed to a string in

$h = @{2 = @('A')}

Whereas if you where to do the below and replace the 2 with a k (an example)

$response = Read-Host 'foo' 
$response
$response -eq 'k'
$h = @{k = @('A')}
$h[$response]
$h['k']

this can be confirmed as well with the below

PS C:\> $h = @{'2' = @('A')}
PS C:\> $h.Keys
2
PS C:\> $h.ContainsKey(2)
False
PS C:\> $h.ContainsKey('2')
True
PS C:\> $h = @{2 = @('A')}
PS C:\> $h.Keys
2
PS C:\> $h.ContainsKey(2)
True
PS C:\> $h.ContainsKey('2')
False

Ah, good point @kilasuit !
