> I don't understand where this array is found

It's a global array, because we have $1, $2, $3, and $10 as well; and it exist as a *10 glob with all the possible slots, array being one of them.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Thanks choroba I figured it was a global, but didn't think that it would have been defined since no regexp match was attempted. I would have expected to get an error when Perl tried to interpolate it as it was not defined. The way forward always starts with a minimal test.	[reply]

An array can't be "not defined", it's just empty. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Yes. What I meant was that I did not expect the scalar `$10` to have been defined and thus that the array would not exist. `$ perl -Mstrict -E 'say $10 ? 1 : 0; say "foo@10bar"' 0 foobar` [download] The way forward always starts with a minimal test.	[reply] [d/l] [select]
