Rather I meant that for one or another reason the debugger steps over each line in both programs. Whereas I would like to explicitly step into the print function or subroutine call to expose for example, the lvalue determinations or aliasing operations. Although on a preliminary read-through of the docs that may be out of scope for the debugger.
