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

But the = is, in turn, an argument operand to defined.

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

    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).
