Stop parsing the current file and move on to a different one
It is rare, but there are times where you want to swap out the currently compiling file for a different one. This module does that. From the point you use the module perl will be parsing the new file instead of the original.
This was created specifically for Test2Harness which can preload modules and fork to run each test. The problem was that using do to execute the test files post-fork was resuling in extra frames in the stack trace… in other words there are a lot of tests that assume the test file is the bottom of the stack. This happens all the time, specially if stack traces need to be verified.
This module allows Test2Harness to swap out the main script for the new file without adding a stack frame.
