For completeness, the arrow stringifies LHS *almost* always...
If your keys start with a number, but also have other characters following
them, or are just completely 'odd' (ie, \W), you must quote them.
For example:
%foo = ( "34foo" => "bar" );
or even
%foo = ( '#)$*.#@' => "bar" );
note that double quotes allow intperlolation, whereas single quotes don't
and of course, the second case may be concidered Very Bad Thing To Do (tm);
keep your hash keys at least half way sane.
