I note that the perlscalar code is careful about multithreading issues
(example: "if we morph to a string, first clear str_val so that after
changing the vtable a parallel reader doesn't get a gargabe pointer"),
but reuses a static PMC* intret.
The current PerlHash PMC coerces keys to strings, so the following will
print bar:
my %hash;
$hash{1} = 'foo';
$hash{"1"} = 'bar';
print $hash{1};
Whereas the nearest equivalent in Python will print foo:
dict = {}
dict[1] = 'foo'
dict["1"] = 'bar'
print dict[1]
For Python support, it would be ideal if there would be a hash method
entry in the VTABLE for each object.
