Wish Type testing in Select - case block

[knutf]

I wish that this code:

Sub Process_Globals
    Type t1(memberX As String)
    Type t2(memberY As String)
End Sub

Sub TypeTesting(o As Object)
    If o Is t1 Then
        Log("t1")
    else if o Is t2 Then
        Log("t2")
    End If   
End Sub

...could be written like this:

Sub Process_Globals
    Type t1(memberX As String)
    Type t2(memberY As String)
End Sub

Sub TypeTesting(o As Object)
    Select o 
        case Is t1
            Log("t1")
        case Is t2
            Log("t2")
    End Select
End Sub

...or like this:

Sub Process_Globals
    Type t1(memberX As String)
    Type t2(memberY As String)
End Sub

Sub TypeTesting(o As Object)
    Select o is
        case t1
            Log("t1")
        case t2
            Log("t2")
    End Select
End Sub

You can restructure your select case to be more like your wish:

'
Select Case True
     Case o Is T1
          Log("t1 type")
     Case o Is T2
          Log("t2 type")
     Case else
          Log("unhandled type")
End Select

Yes, but I still would love to do it in the way I suggest. The "Select Case True" methode is not so intuitive and readable as my sugestion. It is not "true" I want to test, it is the variable "o" I want to test. See this thread:
