in reply to Closure Over Scalar?

my with an assignment is tricky. The declaration of the variable happens at compile time, but the assignment happens at runtime. In this case, the assignment happens after the loop. So, when running the loop, the variable has been declared, but hasn't been assigned to. You need to move the closure block before the loop.

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