Re^4: Constant subroutine main::C redefined

[Corion]

Also note that "redefining" a constant does not necessarily do what BrowserUk wants. The constants get inlined, so redefining them only works from that point on:

use constant C => 1;
sub c { C };

use constant C => 2;
sub d { C };

print c(); # 1
print d(); # 2
