The following ground terms can be used in the first
argument of execution_state/2 (see Breakpoint Predicates). Alternatively, a list containing such terms
can be used. If a given condition occurs multiple times, only the last
one is considered. The order of conditions within the list does
not matter.
break_level(BL)Focus on the current invocation of break level BL. BL is the
break level number, the top-level being break_level(0).
For past break levels, the current invocation is the one from
which the next break level was entered.
inv(Inv)Focus on the invocation number Inv of the currently focused break level.
