I get the same results with either sub, but you don't show the code where you are calling doit_my().

Is it possible that you made a mistake? In the code where you call the local version you have: 

$$x{foo} = join " ", map '"'.doit_local($_).'"', .....

Ie. You are passing $_ into doit_local(), but nowhere in your code is $_ ever assigned a value?

Inside the sub, you then local $_ and assign $_ to it, but you have still never assigned any value, so it is undef, whihch explains the 'uninitialized value' errors.

If I call doit_my($_), I get exactly the same results and errors. What did you pass to doit_my()?
