Because of that, the \RequirePackage command knows an optional
argument that specifies the version date that the loaded package
should at least have. Otherwise LaTeX prints a warning, that
an old package is used, but a newer one is requested.
In case of \aemph:
\atendpreambl...@ifpackageloaded{bidi}{\newcommand*{\aemph}[1]{$\overline{\hboxr{#1}}$}}{}}
Guards can be used:
* \...@ifpackagelater to ensure a appropriate version of package bidi
* checking for \hboxR.
