Auto-declaration has a much older history than that. For example, Fortran 77 (and probably earlier) implicitly typed variables that were undeclared based upon their first letter. Woe to those who forgot implicit none
at the start of every subroutine. I am honestly horrified that Guido thought that declaring variables was a Bad Thing. Larry should have known better too, but at least use strict;
disables that behavior.
