-Why all UDLs are prefixed with ``q_`` instead of just using unit symbol?
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

-Usage of only unit symbols in UDLs would be a preferred approach (less to type,
-easier to understand and maintain). However, while increasing the coverage for
-the library we learned that there are a lot unit symbols that conflict with
-built-in types or numeric extensions. A few of those are: ``F`` (farad),
-``J`` (joule), ``W`` (watt), ``K`` (kelvin), ``d`` (day),
-``l`` or ``L`` (litre), ``erg``, ``ergps``. For a while for those we used ``_``
-prefix to make the library work at all, but at some point we had to unify the
-naming and we came up with ``q_`` prefix which results in a creation of
-quantity of a provided unit.

 Well, this is how [ISO-80000]_ defines it (British English spelling by default).

+Why do we use UDLs reserved for the C++ standard (no `_` prefix)?
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This library is meant to become a part of the C++ Standard Library at some point
+in the future. We decided to work with the target interface to get implementation
+and user experience. Only thanks to this we were able to detect multiple collisions
+with literals already existing in the language in our initial approach
+(`Why all UDLs are prefixed with q_ instead of just using unit symbol?
+<#why-unicode-quantity-symbols-are-used-by-default-instead-of-ascii-only-characters>`_).
+This approach has some side effects though. We had to disable some compiler warnings
+to make it work:
+
+- `/wd4455` on MSVC,
+- `-Wno-literal-suffix` on other compilers.
