Within Google Chrome, I was wondering if stack traces will, in the future, provide mapping support. Currently, using source maps, throwing an error will provide the line number link to my TypeScript files, however... When calling the Error.stack, it gives me the JavaScript lines and files.
Here's a reference picture: http://puu.sh/4DTOG.png
As you'll notice, the actual line the error is on is linked to the TypeScript file, but the stack trace links to the JavaScript files.
There is no inherent technical limitation. However I don't think it is planned. For reasons like, when the stack trace contains code that is not TypeScript (or lacks a sourcemap) etc.
This bug is fixed in chromium 42 :)
