in thread /g matches not really global in scalar context!

Don’t confuse yourself. foreach puts its expression into list context, so a /g match actually returns a list of all matches at once; of course the foreach then iterates over them one by one. The loop construct you want is while, which evaluates its condition in scalar context, so a /g match as the condition will return matches one by one.

Makeshifts last the longest.

    Thanks for making this clear. Is there a way to get all those /g matches at once without a loop?
    OK just found it: 
    use warnings; use strict;
my $x = "aiutino aiutino argh! aiutino";
my @matches = $x =~ / \b aiutino \b /gix;
print "$_\n" for @matches;

    so it is depending on scalar vs. list context what you will get.
    Thanks again,
