Diamond operator iterating over arrays?

trantorvega has asked for the wisdom of the Perl Monks concerning the following question:

Personal test:

$ perl -e '@a = qw/1222 2 3/; while (<@a>) { print $_ ."\n";}'
1222
2
3

From the documentation it doesn't seem the above ought to work, but it does. Anyone knows why?

I think the `<...>` acts as a glob here: `In scalar context, glob iterates through such filename expansions, returning undef when the list is exhausted.` [download]	[reply] [d/l] [select]

That's right, and the array is imply interpolated into the string. You can see that by interpolating an array with items that contain whitespaces: `$ perl -e '@a = ("2 3", 4); while (<@a>) { print $_ ."\n";}' 2 3 4` [download] Perl 6 - links to (nearly) everything that is Perl 6.	[reply] [d/l]
