Re^2: sending data thru a sub routine

... all as a single element, in which case, you need to (for one example) split @ARGV and push its arguments ...

This seems needlessly confusing advice to offer a novice Perler. Literally calling split on @ARGV e.g.:
my @array = split @ARGV;
is likely to produce (unpleasantly) surprising results. Can you be more clear?

Good point: clarification herewith: Some processing is required; it's definitely not a matter of simply splitting @ARGV, because split expects to work on a string, not an array. `C:\>perl -E "my ($input) = @ARGV; my @input = split / /, $input; for $ +_(@input) {say $_;}" "trez zwei uno" trez zwei uno` [download] parenthesize the `$input` to stringify the content of `@ARGV` rather than count its (single here) element(s).

C:\>perl -E "my ($input) = @ARGV; my @input = split / /, $input; for $
+_(@input) {say $_;}" "trez zwei uno"
trez
zwei
uno

parenthesize the $input to stringify the content of @ARGV rather than count its (single here) element(s).
