Indeed thanks! :)

see perlsub for the explanation:

&NAME;       # Makes current @_ visible to called subroutine.

It's a syntax to pass parameters through, so it can't accept new arguments.

  DB<27> sub tst { [@_] }

  DB<28> sub outer { &tst }


  DB<29> x outer(1,2,3)
0  ARRAY(0x2f700e8)
   0  1
   1  2
   2  3

  DB<30> x &tst 1,2,3
Number found where operator expected at

for clarification, while interesting, this doesn't answer my question and side effects are too weird...
