Get variables with call stack

[ANtlord via Digitalmars-d-learn]

Hello! I need to make a some sort of error report system for an 
application. I want to catch base Exception class instance and 
report call stack and with the call stack I want to report all 
variables with their values. There are a couple of services that 
make report using call stack and provides variables' values. 
Sentry.io, New Relic etc.

I see how to get call stack, the book Adam Ruppe writes helps me. 
How to get all variables from every layer of call stack?
