in thread Declare my variable in sysread - Mojo::File::slurp

my $line appears as an argument of defined.

No, it doesn't. It's an operand of =, not defined.

But the = is, in turn, an ~~argument~~ operand to defined. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Yes, `=` is an operand of `defined`, but your whole point is that `sysread($file, my $buf, ...)` is like `defined(my $line)`, but your code doesn't use `defined(my $line)`.	[reply] [d/l] [select]
