I'm using sub _() as a means to localise text
Beside the problem you have with _
having special meaning, the other problem you have is that _ always
lives in main. If you would happen to use a module that also defines a sub _
, you have a problem.
As for your question of restoring magic to _, I'm afraid I don't know the question. I've used sub _ myself before, and ran into the problem, and the problem I mentioned above. I now no longer use sub _. sub __ doesn't have the mentioned problems.
