I realise that's a rhetorical question, but that wouldn't be a very good
idea. Suppose you mistype a local variable and some package happens to
define a dynamic variable with the misspelled name...

Personally, I'd prefer to declare such a variable explicitly, not only
because of the compiler but also because it tells a human reading the
code that they're looking at a dynamic variable.
