What's the big deal?  Perl has an option for flagging undeclared
variables with warnings ("perl -w") or errors ("use strict") and Perl
docs I've seen advise using at least "perl -w" routinely.  Those
didn't have much impact.  Python already has a "global" declaration;
how does it de-Pythonize the language if there's also a "local"
declaration and an option to flag any variable that's not declared as
one or the other?

There's been a proposal from none other than GvR to add optional
static declarations to Python:
