codegeneration support #511

Hi, there!

We have many different compilers/interpretators for different languages. From time to time compilers generate code for the other compilers/interpretators.

For example TypeScript or Ragel.

Lets look into, for example, Ragel.

A user writes code on Ragel and compiler ragel converts the code to C++, Golang, Java, etc.
When the compiler does that it markups codegenerated parts by labels (comments)

// line filename.rl:28

C++, Golang, etc compilers use the tags and if an error or panic exists, that has the file:line in its stacktrace.
See screenshot:

I hope You know that.

Now, I have a question.

We have some codegenerated lua code, that started by gopher-lua.

Is there any way to thace errors like do C++/Golang/Java and Ragel?
