If 'remove' was modified to return the removed value, more compact
syntax would be possible:

delete hash.remove("x");

Also, there would be no need to search for the value twice and
introduce a temporary when the removed value is needed for further
processing:

// do something with the value, for example, pass it to a function
foo(hash.remove("x"));

instead of:
auto v = hash["x"];
hash.remove("x");
foo(v);
