But surely the soul of wisdom is to avoid unintended consequences.
Is it possible to define a subroutine without creating a unique lexical scope for it? Offhand, I can't see a way.
No, But that doesn't completely negate the possibilities of unintended consequences.
Eg. As you follow the fairly common practice of placing your subroutines after your 'main' code; the possibilities for unintentional (and silent) closures abound.
Again, this is utterly without consideration of effects on performance,
Out of context, that sounds like I'm favoring this technique for performance. But if you read back, I'm most definitely not.

that depends on local-izing everything in sight
