The header provides partial specializations of copyable_function for each combination of the possible replacements of the placeholders cv, ref, and noex where
cv is either const or empty,
ref is either &, &&, or empty, and
noex is either true or false.
For each of the possible combinations of the placeholders mentioned above, there is a placeholder inv-quals defined as follows:
If ref is empty, let inv-quals be cv&,
otherwise, let inv-quals be cv ref.
