What's the use case? I think we should encourage to use `Exception#full_message`, and that could default to apply the limit.

In order to be able to output according to "--backtrace-limit" value, I need a API to get this value from the Ruby side. # Proposal I propose a readonly built-in variable "$-B" to get "--backtrace-limit" value. ``` ruby # ruby --backtrace-limit=3 script.rb puts $-B # => 3 ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
