This is a bug report for perl from ivan@bessarabov.ru,
generated with the help of perlbug 1.39 running under perl 5.18.2.


-----------------------------------------------------------------
[Please describe your issue here]

In the perlvar documentation there is a text about @_:

> Within a subroutine the array @_ contains the parameters passed to that
> subroutine. Inside a subroutine, @_ is the default array for the array
> operators push, pop, shift, and unshift.

I think that this is incorrect and should be changed to:

> ... the array operators pop and shift.

The reason behind it that you can use pop & shift without any parameters,
but you can't use push & unshift without parameters, you must explicitly
specify array.

This bugreport is created after the discussion at
https://stackoverflow.com/questions/30960126/how-can-i-use-perl-default-array-variable-with-push
