Re: Using hashref values in constant declarations.(binding)

>  However, why does this work as expected, then?

my @test = ($hashref->{ONE} .. $hashref->{TWO}); 
use constant GOODCONSTANT => \@test;

Short answer: that's how "binding" works!

my (like our ) has dual nature:

• declaration happens at compile time
• assignment at run time

Declaration means the following equally named variables in scope are "bound" to a specific "reference" (saying address would be too simplisti/C) when translated to an op tree.

GOODCONSTANT then points to that reference at compile time, but the content of @test will only be populated at run time.

Try to access content of GOODCONSTANT at compile time, and you will fail.
