I disagree. In the first, you are telling perl that you
want to create a symbol if a certain condition is true.
Maybe under some conditions you don't want to create that
symbol. Consider the same logic applied to hash assignment:
my %foo;
$foo{bar} = 'baz' if $biz;
frob() if exists $foo{bar};
You would expect that $foo{bar} would not exist if $biz was
false. But under your recommendation, it would exist. This
is not the way it should behave.
