using `temp` on a hash key restores its original value when we leave the scope,
while other keys are free to be modified:
m: my %h = foo => 'bar'; { temp %h<foo> = 'meow'; }; say %h
rakudo-moar d4ac15: OUTPUT«{foo => bar}»
m: my %h = foo => 'bar'; { temp %h<foo> = 'meow'; %h<not-foo> = 42; }; say %h
rakudo-moar d4ac15: OUTPUT«{foo => bar, not-foo => 42}»
However, if the `temp`ed key did not exist in the original hash, it WILL exist
after leaving the scope. Expected behaviour: the key does not exist:
m: my %h = foo => 'bar'; { temp %h<not-foo> = 'meow'; }; say %h
rakudo-moar d4ac15: OUTPUT«{foo => bar, not-foo => (Any)}»
