suppress single macro from style file

Question

I have a master style file of macros, which I use for all of my documents. Is there something I can add to the preamble of a particular file so that it ignores some specific macro from my style file?

For example. My style file includes my custom shortcut \foo. Now I am writing a specific document, and I want to use some unusual symbol that is part of some random package I never use. So I add this package to the preamble of this document, to get the command for the unusual symbol. But this package happens to use the command \foo for some other thing I don't care about, and so now I get the \foo already defined error when I try to compile. I would like to add something to the preamble of this document so that it ignores \foo in my style file. Is this possible?

Here is the savesym way of getting rid of this problem:

\savesymbol{foo} should work, after that say \origfoo to access the old version.

The classical conflict appears for example with bbding and marvosym packages:

\documentclass{article}


\usepackage{savesym}

\usepackage{bbding}
\savesymbol{Cross}

\usepackage{marvosym}


\begin{document}

Original version: \origCross

Redefined version: \Cross


\end{document}
