@cast = (
{ name => "pebbles", age => 2, role => "kid" },
{ name => "wilma", age => 31, role => "wife" },
{ name => "fred", age => 36, role => "husband" },
);
print @cast->{age}->{name};
The result here, you see, is "fred", rather than the far more
readily expected "HAVE YOU LIKE COMPLETELY LOST YOUR MIND?".
For a good time, try to guess without running it, what prints
out if you interchange the subscripts:
print @cast->{name}->{age};
Yes, these are all bugs, not features. But hard to fix.
