is there a typical Perl-spell when having a list:
@Array = qw( a b c d );
that needs to be appended from a file:
[somefile.txt]

[EOF]
I'd use
splice @Array, @Array, 0, map{ chomp; $_ } <FH>;
for that, but it may look ugly to others.
Any ideas?
Well, first of all,
splice @array, @array, 0, LIST
is exactly equivalent to:
push @array, LIST
so that's one optimization you could make. As for reading the file and
getting rid of the newlines, I might try to take advantage of a module
like Tie::File or IO::All:
tie my @file, 'Tie::File', 'file.txt' or die "Can't tie: $!";
push @array, @file;
(Tie::File auto-chomps the lines for you. Read its docs for more
information...)
