Truffle and support for a class name 'Object'

[Stefan Marr]

Dear all:

I would like to request a feature:

 Could you please support the class name 'Object' for guest language implementations?
 Or, could you put a big red warning into the Truffle FAQ to avoid it?

If you would consider solution 1, this patch might be useful for some people:

diff --git a/graal/com.oracle.truffle.dsl.processor/src/com/oracle/truffle/dsl/processor/codewriter/OrganizedImports.java b/graal/com.oracle.truffle.dsl.processor/src/com/oracle/truffle/dsl/processor/codewriter/OrganizedImports.java

         if (needsImport(enclosedElement, type)) {
             TypeMirror usedByType = simpleNamesUsed.get(name);
             if (usedByType == null) {


I had a similar patch for Utils.getDeclaredName() which might not be necessary anymore.
However, this one in OrganizedImports is necessary to generate proper specialized classes when using the Truffle-DSL for type specializations.

As mentioned with the original patch, this is also only a work-around. A proper solution might require to check for name clashes directly.

Thanks
Stefan
