           Summary: Compiler generated variables are all using the same
    Classification: Mono
           Product: Mono: Compilers
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: C#
        AssignedTo: msafar at novell.com

xMCS generates the same variable name "<$$>" inside foreach loop (and likely
other places too). E.g.

foreach (AssemblyDefinition assembly in Runner.Assemblies) {
    foreach (ModuleDefinition module in assembly.Modules) {
        foreach (TypeDefinition type in module.GetAllTypes ()) {

will produce several variables named "<$$>". This seems to comes from:

        public static LocalVariable CreateCompilerGenerated (TypeSpec type,
Block block, Location loc)
            LocalVariable li = new LocalVariable (block, "<$$>",
Flags.CompilerGenerated | Flags.Used, loc);
            li.Type = type;
            return li;

This confuse some Gendarme rules into reporting defects that do not exists. I
suspect this can also confuse other tools too (e.g. debugger).
