# Invokes an execution trap to catch the attention of a debugger. This has the
# same effect as placing a breakpoint in debuggers or IDEs supporting them.
#
# Execution is allowed to continue if the debugger instructs so. If no debugger
# is attached, usually the current process terminates with a status that
# corresponds to `Process::ExitReason::Breakpoint`.
#
# Inside an interpreter session, this drops into the REPL's pry mode instead of
# a system debugger.
