ok, I get it. But these two philosophies can meet...probably they
should meet!
I did not seriously analyze the whole code, but I thought from the
beginning that
having a bignum method was strange and that the only logical reason
was some
hidden and old software/hardware constraint. So that "respectful"
should maybe try to evolve, putting some flexibility in some too
strict code parts.
So the other, more aggressive philosophy could build upon the
common base, letting the hardware "express itself" a bit more where it
is possible.
I don't mean to be respectless to other's work - I'm even new here in
the list - but I don't think
the fact that there is a lot of different hardware to support can be
the reason not to
evolve, at least not for a long time.
That being said, I'd probably better go and code something instead of
I'll do asap. And...I won't ask about that spectrum analizer idea back
in 2000... ;-)
