Hi Matthias,
Bravo is inspired by the PHP template engine Smarty and the Haskell
Smarty is also about caching. Can you say whether your library support
kind of caching as well?

Hi!
I'm trying to get cabal build my toy compiler, which is based on llvm
bindings on hackage. Everything is fine with ghc --make,
but with cabal install I get:
Loading package llvm-0.7.1.1 ... command line: can't load .so/.DLL
for: LLVMSystem (dlopen(libLLVMSystem.dylib, 9): image not found)

This doesn't address the space leak, but your parseChromosome function
looks very inefficient - isInfixOf is repeatedly checking the prefix
chromosome for C1 to CY. If you have a lot of CY's in a file then it
will do a lot of work parsing them.
The cleanest way of handling this would

Ah, I see, I was looking at the example code in the Happstack documentation
you linked. Looking at the documentation of Network.Socket I can see where
it provides an option to bind on a particular address. The example given in
the Happstack docs uses bindPort to get the socket which confused me as

However, with optimisations turned on... GHC knows that sum is

GHC does that when optimizations are turned on, but that behavior

difference is that Bravo parses the templates

Thank you for releasing this library, it looks very intriguing. I've been

always irks me is that- while the rest of my program is checked at

This sounds like homework.
Think in abstract terms what you want to accomplish.
Start with the simplest case first, usually the base case.
