public class StaticCompilationTransformer extends ClassCodeExpressionTransformer
Some expressions use symbols as aliases to method calls (<<, +=, ...). In static compilation, if such a method call is found, we transform the original binary expression into a method call expression so that the call gets statically compiled.
