It would be nice if there was a way to prevent the following typo-style errors for hashrefs, as 'strict' does for vars:

my $href = { key1 => 'foo' };

.
.
.

if ( $href->{key_1} eq 'foo' ) {
 # celebrate wildly
}

Of course, one could use 'defined' to tighten up the code. But it would be nice to stop hashrefs being accidentally abused somehow. As far as I know though, this is not really possible in a strict-like way, only on an ad-hoc basis. Any thoughts?
