Template ? focus on PHP5

I was hacking away at the Compiler backend for Template the other day, and it became clear that there is alot more work in refactoring the Flexy code (let alone looking at the Block Backend) Considering this may take many months before it delivers anything more than what Savant currently is, what are your thoughts on making Template a PHP5 only package?. eg. a) Throws PEAR_Exception, on anything that could cause the using application problems. b) use extra arguments for warnings ?? - until a lightweight warning mechansim can be worked out.. c) use all the protected / private etc. d) Type Hints Regards Alan -- Can you help out?
