What I want to do is ask the user for a number of strings to read into an array, and then ask the user to input that number of strings and read them into the array. When I run this code it never asks me for an input the first cycle of the first for-loop, just prints out "String #0: String #1: " and then I can input text. Why is that and ...
Is it possible to have a (fixed) array which stores its elements in the read-only segment of the executable and not on the stack? I came up with this code but unfortunately it is very unflexible when it comes to adding, moving or deleting items. How do I verify that the strings are indeed stored in the read-only segment? I tried readelf ...

The following code works due to @_ aliasing magic, but seems like a bit of a hack to me: my @a = 1 .. 10; my $b = sub{\@_}->(@a[2..7]); @$b[0, -1] = qw/ < > /; print "@a\n"; # 1 2 < 4 5 6 7 > 9 10 ...
