That seems contrived. I can't imagine a single case where I'd do it this way, rather than 
my ($firstkey)   = grep {/key$/} @list;
my $numberofkeys = grep {/key$/} @list;

I could see that usage if you were doing @firstkey[$of_list_nr_x], but then that doesn't emit a warning.

Unless your point is that the warning breaks orthogonality, which is not an argument I care about here.

Makeshifts last the longest.
