Returns appropriate type sugar for constructing a successful result or outcome, usually success_type<T> with a decayed T.

Two default overloads are provided, one taking a single required parameter with optional spare storage value parameter returning success_type<std::decay_t<T>> and perfectly forwarding the input. The other overload takes no parameters, and returns success_type<void>, which usually causes the construction of the receiving basic_result or basic_outcome’s with a default construction of their value type.

Overridable: By Argument Dependent Lookup (ADL).

Requires: Always available.
