One of the pragmatist philosophers (James?  Dewey?) used to talk about
the "cash value" of things -- i.e., what difference did it make.  It's
reasonable to think that way.  But it's not so reasonable to insist that
the only thing that matters is "money-earning software".  I do not think
that commercial considerations full stop should decide any issue.

That said, however:

But for me the deciding factor is that I can write circular constants
in source code.  I don't like the idea of a language that can't compile
its own source notation.  (#. is a pain, but I'm willing to keep it).
