Splices of the form +x or +int x are not implemented in either the interpreter or the compiler. Issue #1930 already hints at this. This is a reminder to implement...

**Setting the stage** Module `vis::Graphs` contains a data declaration that goes like this (heavily abbreviated): ``` data CytoLayout(CytoLayoutName name = dagre(), bool animate=false) = cytolayout() | breadthfirstLayout(CytoLayoutName name = CytoLayoutName::breadthfirst(),...

After merging rascal and rascal-core we have already eliminated most duplicate files. This issue documents the remaining, potential, duplicates, handle with great care: - [x] `JavaCompilerException.java`: **[likely merge]** - `org.rascalmpl.interpreter.utils.JavaCompilerException.java`...
