> Under the OP's "proposal", you would still be able to do

I can't see that the OP made a proposal just a fuzzy wish and linking to a thread where I coined the term automine and already highlighted the problems.

Your example is redundant, cause the obvious rule is that any assignment in a new scope equals a declaration.

So what's the proposal now?

Python has IMHO

• rather complicated rules, (which changed again in Py2.2 for enclosed )
• no block-scope, no loop-scope, just (nested) function-scopes ( def )
• no my to support, but the inverse nonlocal for Py3
• it's hoisting declarations to scopes start

These rules only look easy on simple cases, but closures are rather fuzzy. Given that most Pythonistas have a rather simple worldview, they don't miss closures.

This model is very hard to transfer to Perl.

Where would we steal? Ruby? Javascript?

JS is a mess, a var is

• like our outside a function
• like my inside a function
• is hoisting

JS had to introduce let to have a proper my plus an optional strict

So again WHAT is the proposal???

For the records: I'd love to be able to have an automine pragma which makes easy cases easy and complicated cases feasible.
