> Suppose we have a DML file named "example.dml" that contains a source call to itself:
> {code}
> source("./example.dml") as example;
> {code}
> This produces an infinite loop that gives:
> {code}
> Exception in thread "main" java.lang.StackOverflowError
> {code}
> Similar error occurs for other types of circular references such as script1 imports script2 imports script3 imports1.
