Interestingly, this one tweak to the whitespace rule also means that we'll
be able to simplify the parentheses out of other similar built-in constructs:
if $foo { ... }
elsif $bar { ... }
else { ... }
while $more { ... }
for 1..10 { ... }
I think throwing out two required

Err. Expressions don't have their own scope level, ev

The only way to declare a lexical variable outside a block for use only
