The try block needs to happen and be returned and not continue the TCO loop. If it does then the successful result of a try block gets evaluated an extra time so something like this `(try* (list 1) (catch* e (prn :e e)))` will cause an exception. If an exception occurs, then the catch block of a try/catch can loop/TCO without issue but not the initial try form/block. |

Compilation notes
Mac OSX
This C++ implementation was developed on Mac OS X Yosemite, and uses the stock g++ compiler.
The only other requirement is GNU Readline, which I got from homebrew.
brew install readline
You may need to edit the READLINE path in the Makefile.
Ubuntu 14.10/15.04
This should compile on Ubuntu 14.10 and 15.04 with the following packages
apt-get install clang-3.5 libreadline-dev make
Docker
For everyone else, there is a Dockerfile and associated docker.sh script which can be used to make and run this implementation.
* build the docker image
./docker build
* make the MAL binaries:
./docker make
* run one of the implementations:
./docker run ./stepA_mal
* open a shell inside the docker container:
./docker run
