Sometimes one need less information (or more information) associated with backtraces.

It would be nice if one could send in a separate flag informing the VM about the granularity of information required, eg: 

caller_locations(0,-current_depth, BacktraceInfo::Label & BacktraceInfo::Lineno)

This allows for one to take quicker backtraces if they need less information, additionally BacktraceInfo::Bindings and BacktraceInfo::Klass could be added which allow you to gather more information for heavy profiling / diagnostics.
