The -w switch is much more informative.

You may now define BEGIN and END subroutines for each package. The BEGIN

Saying "shift @foo + 20" is now a semantic error because of precedence.

The elements of argument lists for formats are now evaluated in list
context. This means you can interpolate list values now.
