Er... hip hip hurray?!?!
This is precisely the reason why I came up with the raw idea of
highlander variables in the first place: because it's annoying not being
able to access a hash passed to a sub through a hash reference, in the
normal way. Not unless you do aliasing through typeglobs. A highlander
variable would get you that: that if a hash %foo exists, the scalar $foo
would automatically be a reference to that hash.
But, if there won't be full blown highlander variables, how does Perl
know if by $foo{THERE} you mean an item of the hash %foo, or a item in a
hash referenced by the hashref $foo?
