No, my only current "for-real" thing still relies on recursively
dependent modules (and found a GHC bug where it choked on them too, so
I'm not making much progress on it currently... along with having other
things to do, (like find obscure bugs in Yhc :))


In fact this is in my Main.lhs, and I don't believe it would be affected
by these bugs:

Avoid non-explicit use of floating-point numbers -- they're inexact,
platform/machine-dependent, and mostly unnecessary.
Of course relying on defaults at all will be generally avoided.
In fact, since these defaults are confusing and rare, disable them
altogether.
In particular, they are the only thing besides the also-bad monomorphism
restriction
that make module boundaries significant -- so make sure to disable
defaults in every
module, like this:

> default ( )  -- defaults are bad, see Main

BTW it's an attempt to reimplement RoboWar in Haskell, and the code is
coming out much cleaner than the original (which was written in C only
for Mac pre-OSX), but after about a week of working on it earlier this
summer I stopped when I could only compile it with GHC 6.5.something
(though the GHC bug will be fixed in 6.4.3, and if I felt like it I
might be able to add workarounds to the .hs-boot files...)
