Hi perl-diddler,

So how could it cause confusion?

You as the author may be able to keep track of the keywords vs. subs, and Perl may be able to resolve the ambiguity most of the time, but it's not too difficult to accidentally cross the line where Perl may pick the wrong definition (for example, there's the warning "Ambiguous call resolved as CORE::continue(), qualify as such or use & at ..."). Also, another reader of your code (including a future maintainer - or even your future self) could easily become confused between next and &next, etc.

It's just one of those cases where as long as you know what you are doing and your script isn't intended for distribution then it's probably fine; but if you do intend the code for a wider audience then I was just pointing out that there are some good rules of thumb / conventions, such as not to define subs with the same name as Perl builtins unless you intend to replace them, and that constant names are typically uppercased.

Regards,
