With => quotes around the keys are not -always- required. The quotes are
required if the key isn't an identifier (matched by
/^[A-Za-z_][A-Za-z0-9_]*$/) or a number, or some notable exception.
Consider:
%foo = (
foo-bar => 1, # tries to subtract 'bar' from 'foo'
-test => 2, # key "-test"
foo() => 3, # calls the function foo()
900 => 4, # key "900"
);
So => does what you mean, usually, but it does not always auto-quote its
left side.
