Module lookup and class naming

Hello,


I'm using a custom module for dealing with CSV files for some years now, and everything's fine :

— 8< — 8< — 8< — 
// Public.Standards.CSV.FILE
class FILE
{
  inherit Stdio.FILE;
  // custom code here, everything's fine
}
— >8 — >8 — >8 — 


Now, i'm slightly updating the module to handle CSV data stored in strings :

— 8< — 8< — 8< — 
// Public.Standards.CSV.String
class String
{
  // obviously won't inherit String here
  // class name collision : can't invoke classes from top level String, like String.SplitIterator for example
}
— >8 — >8 — >8 — 


This leads me to two questions :

1- Invoking String classes (like String.SplitIterator) from my String class fails because of class name collision. There should be a way to ask the compiler to look up String.SplitIterator from the top level hierarchy and not the local class but i failed to find this myself from the doc.

2- Obviously, renaming the String class solves the issue. Should class names be globally unique ? Public.Standards.CSV.CSVFILE and Public.Standards.CSV.CSVString looked redundant to me.


Thank you,
