Write the same thing without syntactic sugar from constant.pm.

Mmh. I see constant.pm does very little.
Well, it nicely sets things up for the compiler to optimize.
perl -MO=Deparse -e 'use constant PI => 3.1415; print PI'
use constant ('PI', 3.1415);
print 3.1415;
-e syntax OK
Greg's version gets optimized as well:
perl -MO=Deparse -e'sub PI () {3.1415} print PI'
sub PI () { 3.1415 }
print 3.1415;
-e syntax OK
