To be perfectly clear, ByteString and Text target much different
use-cases and are hardly interchangeable. While ByteString is, as the
name suggests, a string of bytes, Text is a string of
Hi Clark,
How is this a problem?
If you're representing text, use 'text'.
If you're representing a string of bytes, use 'bytestring'.
If you want an array of values, think c++ and use 'vector'.
the problem is that all those packages implement the exact same data

Well to me, that is not the main issue. The main issue is that you have

I really don't understand this concern.

Where can I find this? I can neither in the array package nor with

You can argue that for any benchmark, but sometimes the choice is
between Apples and Frogs. If you have some more extensive benchmarks I'm
happy to

It seems that the laziness of String or [char] is the problem.
My question boils then down to this. There are plenty of Haskell FFI
examples where simple things like sin/cos in math.h can be

cabal-dev ghci does work with hsc2hs, but only because it doesn't interpret
your source. Rather, cabal-dev ghci loads ghci using the sandbox install
of your package, which is less useful for a variety of reasons.
Aside from that detail, I wouldn't gain any benefit from having this
feature built
