Not in the least. "soon" is also a gross overstatement. ' What's the size/difficulty of compiler spotting this? Suppose it needs to be able to 'look ahead' by few statements - which I'd thought it does already to some extent. Think I saw email where you said 'few' months - that is soon in context of fpc and even more in the context of significant fpc changes, so not 'gross overstatement'!
