In case it helps, warn gets its info from the most recently executed nextstate op.

$ perl -e' if ($false) { # This is line 2 } elsif (warn) { # This is line 4 } ' Warning: something's wrong at -e line 2. $ perl -MO=Concise -e' if ($false) { # This is line 2 } elsif (warn) { # This is line 4 } ' 6 <@> leave[1 ref] vKP/REFC ->(end) 1 <0> enter ->2 2 <;> nextstate(main 4 -e:2) v ->3 - <1> null vKP/1 ->6 4 <|> cond_expr(other->5) vK/1 ->7 - <1> ex-rv2sv sK/1 ->4 3 <#> gvsv[*false] s ->4 - <@> scope vK ->- 5 <0> stub v ->6 - <1> null vK/1 ->- 9 <|> and(other->a) vK/1 ->6 8 <@> warn[t2] sK ->9 7 <0> pushmark s ->8 - <@> scope vK ->- a <0> stub v ->6 -e syntax OK
