In Vim, how can I search for the contents of a register?

Question

Say I've yanked the text "foo" into register x. How can I search my file for the contents of that register?

I know that I can type / to search, then Control+R followed by x to paste the contents of that register, leaving me with /foo. But I'm trying to use the name of the register instead.

For example, I tried /@a, but that doesn't work.

That's basically the easiest way to do it. If you want to script it, you could use something like this:

:execute '/' . @x
