Friend Partial Class DataFlowPass
''' <summary>
''' Collection of 0, 1 or more slots. Allows returning of several slots by some
''' DataFlowPass methods to handle cases where implicit receiver represents
''' several variables, like in:
''' Dim a, b, c As New C(...) With {...}
'''
''' Because such constructions are very rare in real user code, the collection only
''' allocates an array builder for storing several values if there are indeed more
''' than one slot to be stored. Because the collection may optionally create an
''' array builder, collection's Free() method must be called when appropriate.
'''
''' Note that the collection is mutable, so one can add or modify the values.
''' If some collection elements get replaced with 'SlotKind.NotTracked' collection
''' does NOT "shrink", i.e. once allocated the array builder is not freed even if
''' all the elements are set to 'SlotKind.NotTracked'.
'''
''' Collection cannot store 'SlotKind.Unreachable' (0) which has a special meaning.

' ======= 11.6.1 Identical Type and Member Names
' It is not uncommon to name members using the same name as their type. In that situation, however,
' inconvenient name hiding can occur:
'
' Enum Color
' Red
' Green
' Yellow
' End Enum
'
' Class Test

' Get
' Return Color.Red
' End Get
' End Property
'

' Return Color.Green ' Binds to the instance property!
' End Function
' End Class
'
' In the previous example, the simple name Color in DefaultColor binds to the instance property
' instead of the type. Because an instance member cannot be referenced in a shared member,
' this would normally be an error.
'
' However, a special rule allows access to the type in this case. If the base expression
' of a member access expression is a simple name and binds to a constant, field, property,
' local variable or parameter whose type has the same name, then the base expression can refer
' either to the member or the type. This can never result in ambiguity because the members
' that can be accessed off of either one are the same.
'
' In the case that such a base expression binds to an instance member but the binding occurs
' within a context in which "Me" is not accessible, the expression instead binds to the
' type (if applicable).
'
' If the base expression cannot be successfully disambiguated by the context in which it
' occurs, it binds to the member. This can occur in particular in late-bound calls or
' error conditions.
