I think anybody who is coding with strict/weak/contract type-enforcement/casting is going to understand try/catch/Exceptions... Granted, the people using that code and maybe stuck maintaining it could be in for a steep learning curve. But I don't think an Exception being thrown will be problematic for the original coder using this type-hinting stuff. PS The contract stuff looks kind of cool, but seems too unwieldy for pre-parsers/IDEs/lint type tools, so I'd have to vote "nay" on it, if my svn access to docs gives me a vote... -- Some people ask for gifts here.
