'my' variables are lexical to the enclosing block. Here, since the variables are declared in the MAIN package, outside of any block, they are global, or visible to all all blocks within the package MAIN.

Almost. They have file scope, they're global to the file. See Lexical scoping like a fox,

$ cat my $foo = qq{i'm in main too ${\__FILE__}\n}; sub foo1 { print $foo; } $ cat my $foo = qq{i'm in main too ${\__FILE__}\n}; sub foo2 { print $foo; } $ perl -e " require $_ for qw/ /; foo1(); foo2(); " i'm in main too i'm in main too
