Carter: we don't have both. We have one function from each category. My
guess is nobody's ever really needed a really fast zipWith ::

I did use that a couple of times (`xor`ing 2 ByteStrings together), and was
surprised by the omission back then, but IIRC (can't validate now), there's
a specialised zipWith (as proposed) in the module (with some other name,
obviously), which is not exported, but used when you 'pack' the result of

Cucumber seems to be great if you mainly want to read your code
over the telephone, distribute it via national radio broadcast, or
dictate it to your secretary or your voice recognition software. You can
program thus without having to use you fingers. You can lie on your back

This version provides new APIs. Thus, version is now 1.0.0. The design

Enjoy!

I've just read Semantic Versioning (SemVer) [1], Package Versioning Policy

Is PVP the one that every package on Hackage should use?
SemVer seems to make more sense to me.
Also, ECT looks very promising, but it is dated back to 2005 and I
