Please compare these outputs of B::Deparse and B::Concise °

C:\>perl -MO=Deparse -e "my DB $x; print $x"
my DB $x;                                       # <-- DB
print $x;
-e syntax OK

C:\>perl -MO=Concise -e "my DB $x; print $x"
8  <@> leave[1 ref] vKP/REFC ->(end)
1     <0> enter ->2
2     <;> nextstate(main 1 -e:1) v:{ ->3
3     <0> padsv[$x:1,2] vM/LVINTRO ->4          # <-- no DB
4     <;> nextstate(main 2 -e:1) v:{ ->5
7     <@> print vK ->8
5        <0> pushmark s ->6
6        <0> padsv[$x:1,2] s ->7
-e syntax OK

So where is the information hidden in the OP-tree, such that Deparse can see it but not Concise?

Please enlighten me! :)

°) for simplicity I just randomly picked a predefined package DB (debugger) as a dummy type.

update

Devel::Peek neither helps 

C:\>perl -MDevel::Peek -e "my DB $x=10; Dump $x"
SV = IV(0xee96a8) at 0xee96b8
  REFCNT = 1
  FLAGS = (IOK,pIOK)
  IV = 10
