COMPILE_IF_MUTABLE(QUERY_TYPE, RETURN_TYPE)

A help macro to simplify conditional compilation based on mutability.

Copyright

        This macro just wraps the SFINAE paradigm and enables compilation only if the
        QUERY_TYPE is mutable. This macro is replaced by RETURN_TYPE in this case. If
        QUERY_TYPE is const, the code following this macro invocation will not be compiled.

Parameters:

QUERY_TYPE – The query type to be checked for mutability.
RETURN_TYPE – The return type generated if compilation succeeds.
