Message:
Getting rid of indirect object syntax new calls. Quoting perlobj:

> But what if there are no arguments? In that case, Perl must guess what
> you want. Even worse, it must make that guess *at compile time*. Usually
> Perl gets it right, but when it doesn't you get a function call compiled
> as a method, or vice versa. This can introduce subtle bugs that are hard
> to detect.

> For example, a call to a method "new" in indirect notation -- as C++
> programmers are wont to make -- can be miscompiled into a subroutine
> call if there's already a "new" function in scope. You'd end up calling
> the current package's "new" as a subroutine, rather than the desired
> class's method. The compiler tries to cheat by remembering bareword
> "require"s, but the grief when it messes up just isn't worth the years
> of debugging it will take you to track down such subtle bugs.
