Why can't I access lexical variables through a typeglob?
perl
Solution
Lexical variables (those created with `my`) are not part of the symbol table, so they cannot be reached by globs. See also Of Symbol Tables and Globs.
Problem
I don't understand why the example below fail (test 2). Why I cant access the variable bb from the *bb glob? ``` use Test::More tests => 4; $aa = 1; my $bb = 2; # HERE! local $cc = 3; our $dd = 4; is(${*aa}, 1, "$ \*aa should be 1"); is(${*bb}, 2, "$ \*bb (my) should be 2"); is(${*cc}, 3, "$ \*cc (local) should be 3"); is(${*dd}, 4, "$ \*dd (our) should be 4"); ``` The output is ``` 1..4 ok 1 - *aa should be 1 # Failed test '*bb (my) should be 2' # at untitled line 10. # got: undef # expected: '2' # Looks like you failed 1 test of 4. not ok 2 - *bb (my) should be 2 ok 3 - *cc (local) should be 3 ok 4 - *dd (our) should be 4 ``` Under perl 5.16.0 Thanks
