It's good to see you're paying attention to deprecation warnings.

You can use the splice function to remove elements from an array. Here's an example: 

$ perl -Mstrict -Mwarnings -E '
my @x = qw{a b c};
say "@x";
splice @x, 1, 1;
say "@x";
'
a b c
a c

If you know the value you want to delete but not the array index of that value, grep may be a better option: 

$ perl -Mstrict -Mwarnings -E '
my @x = qw{a b c};
say "@x";
@x = grep { $_ ne q{b} } @x;
say "@x";
'
a b c
a c

Also, an empty list will not add elements to the array, e.g. 

$ perl -Mstrict -Mwarnings -E '
my @x = ( qw{a}, (), qw{c} );
say "@x";
'
a c

You might use this feature in, for instance, a map statement. This example shows discarding certain values and modifying the remainder: 

$ perl -Mstrict -Mwarnings -E '
my @x = qw{a b c};
say "@x";
@x = map { $_ ne q{b} ? uc : () } @x;
say "@x";
'
a b c
A C
