Something I think about when I read about things like this whether there
some sort of unifying principle that could be used in other debuggers or
for other similar sorts of programs. Is there some support that a debugger
should be providing to make things like this easier?

I recently I've written Devel::REPL plugins to call a trepan or perl5db
debugger from re.pl via Enbugger.
If there are other plugins for this, I'd be interested to compare.
https://github.com/rocky/Perl-Devel-Trepan-Shell has the code.
In my repl.rc load the plugins:

The breakpoint is still set - it is just a warning. There are many ways
that this heuristic can fail. For example setting a breakpoint on a line
with:
use English; $x = 3;
may "skip" the "use" and still stop on the assignment statement.

With the recent release of Devel::Trepan (0.1.4), I am at a juncture of
next steps. So I thought I would solicit feedback.
The good news from my standpoint is that things are good enough for my
needs. And I can be picky. Devel::Trepan has been tested on a number of
Unix platforms thanks to CPANTS.
I was looking at old debugger list postings on "accelerated stepping".
The general problem of how to make stepping feel right is a well trodden
topic. So let me describe how the trepanning debuggers such as
Devel::Trepan partially address this. The idea builds on something Kent

In working on the Trepanning debugger for Perl which in large part is
modernizing and modularizing perl5db, I keep running into the limitations
of eval.
In both Ruby and Python, one can pass arguments in addition to the string
to evaluate which controls the environment or context that evaluation u
As Shrek says when he first entered Duloc: ``It's quiet here... Too quiet!''
A little while ago I asked if there was a way get get some sort of object
which indicates the exact position from caller. Again, line number doesn't
really cut it since there can be many statements on a line.
I just ran
ts on a single line.

With much trepidation, recently I started porting my trepanning debugger to
Perl.
Perl has always had a really good debugger, so said above, I undertook this
with some hesitation.
As someone who doesn't always work in Perl, the stock Perl debugger,
perl5db.pl has always felt to me a little bit of
