> You can do this with PadWalker.
Thank you. I haven't tried it yet, but documentation of PadWalker
from CPAN declares a var_name() function that seems to be exactly what
I want.
Apparently this was a tricky feat. From the documentation: "I
wouldn't recommend using PadWalker directly in production code, but
it's your call. Some of the modules that use PadWalker internally are
certainly safe for and useful in production."
And from a review: "PadWalker is really, really useful if you need to
debug something really, really weird. I hope you never have to use
this module, but if you do, use it boldly."
:-|
Thanks for all the help. I'll probably give PadWalker a try next time
I am feeling bold, and have a little time to spare before production.

and i doubt you have a legit reason to need this in production code. i
smell an XY problem here. when someone needs to use such a dark magic
solution, i say the problem is poorly specified or similar. tell us what
the real problem is, don't ask how to do something requiring magic. i
can find no good reason (other than debugging or wacko stuff) for
needing the name of a variable. and if you have anon references, you
can't get any name.

(say that I'm wrong) Did you give up on debuger?
