Thanks for pointing it out the test file. It wasn't in Gforth 
0.7.9_20160113 for Windows that I've been using, and I missed finding it 
in the GIT repository as I expected to see it in the test directory.

Regarding cost/efficiency of CATCH/THROW I'm not sure whether it will 
make a great difference for me in practice given the power of desktop 
computers. I might rethink it in future if speed is a problem.
