It does. "use SVN::Core" (or "-MSVN::Core" on the command line) is
exactly equivalent to:

     BEGIN {
         require SVN::Core;
         import SVN::Core ();
     }

(see "perldoc -f use" for details). The "require SVN::Core;"
essentially places the entire contents of SVN/Core.pm inside that BEGIN
block, which has the effect of causing the

     our $gpool = SVN::Pool->new_default();

line to be inside the BEGIN block, which is why it executes.

The fact that there's a BEGIN block inside SVN/Core.pm is a bit of a
red-herring.
