what would happen if someone pass the code through a automate code translator ... say Perl 5 to Perl 6 or Fortran77 ... god knows. What would happen then?

Given how much existing Perl 5 code relies on these initialization semantics, any Perl 5 translator that did not understand these semantics, and translate accordingly, would be pretty useless.

Knowing the primary author of the upcoming official Perl 5 to Perl 6 translator, I doubt he'll have any difficulty with Perl 5's longstanding initialization semantics. :)
