tl;dr: Breakages without upper bounds are annoying and hard to solve for
package consumers. With upper bounds, and especially with sandboxes,
breakage is almost non-existent.
I don't see how things break with upper bounds, at least in the presence of
sandboxes. If all packages involved follow the

I found [1] a few months ago. It outputs Java bytecode, so it should work
on android. Given that Android development in java is very well supported
in eclipse, you might want to use haskell/frege only for the internals of
your program and keep coding your interface in Java.

I don't think there's enough information in the snippet you've given to
determine what the problem is. And in general, it's a good idea to include

Ok, there were only minor differences between the repo and the version on

same as version 1.3.7 on hackage.

Especially in the case of base, not sure how upper bounds help at all:
If incompatible, you break with or without upper bounds. Actually getting
errors related to Num instances is more informative IMO.
If compatible, you just get false negatives and errors.
In either case cabal can't install

Out of curiosity: wouldn't it make more sense to focus on the
other direction (calling Haskell from V8)? Roughly like:
I guess it really depends what you are after. If you want to cabalize
existing JS libs, then I think bindings to V8 make perfect sense ;)
