The major drawback of using perl `constant` is the fact that they do
not interpolate like variables in most of the contexts (those who
automatically quotes barewords). Like said on Perl Monks here , you
have to do some "tricks" depending on the context in which you're
using the constant and that's not really "clean".
But maybe trading clean for another package is not worth it. I just
searched for alternatives way of doing it and none seems to be in the
core packages so maybe we should just drop this.
