* Use merge2, gulp-if, gulp-newer, and more projects * Add watch task * Working non-inline sourcemaps for runtests * browser tests now also loads sourcemaps from disk * Lazypipes and better services stream management * export interface used by other exported functions * Make goto-definition work for `this` parameter * Add new error for rest parameters * Add error message for rest parameter properties * Fix case when a document contains multiple script blocks with different base indentations. Use the base indent size if it is greater that the indentation of the inherited predecessor * Fix rwc-runner from breaking change in compiler (#9284) * Signatures use JSDoc to determine optionality * Changed implementation to use closure * Updated tests * Fixed linting error * Adding Code of Conduct notice * Don't crash when JS class property is self-referential.

Fixes #9527
The out-of-memory error happens when a class has a property that's not initialised in the constructor and a method that returns
this. Thanks to @vladima for debugging and finding the fix.The property that's lazily initialised outside the constructor causes an error (that will ultimately be discarded instead of reported). In the course of constructing this error message, the compiler tries to stringify the ES3 'class'. Unfortunately, Salsa represents ES3 'classes' as anonymous types. The stringify code assumes that anonymous types aren't circular, but methods that return
thisactually cause a circularity.The simplest fix is to change ES3 classes not to be anonymous types. However, we should consider not even producing checker errors in Salsa since they will be discarded, even though they may be quite expensive.
