+  // embeds absolute build-time paths to core library sources into Kernel
+  // binaries this introduces discrepancy between how stack traces were
+  // looked like in legacy pipeline and how they look in Dart 2 pipeline and
+  // breaks users' code that attempts to pattern match and filter various
+  // irrelevant frames (e.g. frames from dart:async).
+  // To work around this issue we reformat urls of scripts belonging to
+  // dart:-scheme libraries to look like they looked like in legacy pipeline:
