I want those constants > available to users of package Foo, so the following code would work: > > === foo.pl === > package foo; > use constant VAR => "someval"; > > === bar.pl === > use foo; > print $foo::VAR; > > It doesn't appear to be working; it compiles ok, but it prints > nothing. I thought it would print "someval". > That looks interesting. How do people use that kind of constant assignment. I can see uses for it, but would be interested to hear what others use this technique for.
