include() suggestion

I didn't know where else to post feature requests so I'll post it here. Could we get included files to not merely be sucked in to the file that is including it but still think of it as a distinctive file in terms of getting debug output for errors. The reasons for this are 2 fold: 1) You could see all the files run by a particular page and not have to trace through files to see all the files which are called during a request to the server. 2) For error messages, it would give you the line number of the particular file that has the error and not the line number of the merged single file. For anyone who has used Cold Fusion, you'll know what I mean by how this should work. This would be a MAJOR improvement for making debugging during development easier. Thanks. Steve
