As well as the license, there's also two technical details that need to be addressed to fit with the features of dmd EH. 1) Exception chaining - still on my todo 2) OOM exceptions could be handled better. By all means, I'm happy with you to use it as a point of reference. What you'll find is that pretty much all GCC frontend personality routines are essentially identical, barring the of handling it's own exception object / data. Iain.
