Well a compile-time constant with varying refs? Looks pretty much like just another constructor like  to me.
use strict; use warnings; use Data::Dump qw/pp dd/; use constant a => 1; $\="\n"; print \1; # SCALAR(0xdf00e0) print \1; # SCALAR(0xdef540) print \(a); # SCALAR(0x2a19c70) print \(a); # SCALAR(0x2a19c70)
