the way i understand https://docs.perl6.org/language/var
You can create your own $*ARGFILES.
sub MAIN ( +@ARGS ){
my $*ARGFILES = IO::ArgFiles.new( @ARGS || $*IN );
.say for lines;
}
Note that IO::ArgFiles is now only just a subclass of IO::CatHandle.

wow ... thanks for pointing this. still can't mix MAIN and ARGFILES but
learned. thank you very much.

for optional options like -H, use "multi sub main" - then you can have
different sets of options available without having to fiddle with *@rest

Isn't that just `slurp.chars` ?

Isn't that just `+words` ?

hello people,
short question: how to use $*ARGFILES in a MAIN function?
context:
as an exercice as well as demo, i reimplement unix filters
(cat, grep, wc, join, paste, ...). Basic wc could be
multi sub MAIN ( :$l ) { say +lines }
multi sub MAIN ( :$c ) { say [+] lines>>.chars }

Propose change to $*ARGFILES inside MAIN
Make $*ARGFILES := $*IN or IO::ArgFiles.new($*IN) inside sub MAIN
