I'm not sure what exactly you're asking or what you are trying to achieve using the Perl read-only variable $`.
Can you give us an example of what you're trying to do? It could help us to answer your question more specificaly.

use the constant pragma, like this:
print foo;[/b]
constants may be hashes, arrays, subroutines, etc.....
