Why should this be an issue? Just because you can't diddle $foo doesn't
mean you can't diddle the *foo typeglob.

Coming soon from a Larry near you:
At some point, we'll enable the use of a C<constant> attribute
on variable declarations:
my $PI : constant = 4 * atan2(1,1);
This has all the advantages of being a variable rather than a
subroutine. It has all the disadvantages of not being implemented yet.
