Comment:

 As great as it would be to have this, I believe it is unrealistic within
 the scope of GHC. The code that is run by GHC has little resemblance with
 the original source code, and `[1..3]` does not step to `[2,3]`, for
 example.

 The closest support for this is the GHCi debugger, see the user’s guide
 for it. But it is more suited for experienced developers.

 There might be dedicated tools for teaching out there that do that.
