@jpf91 - I think that a program crashing abnormally because something threw inside a nothrow function, although may not be seen as desirable, should be considered acceptable behaviour in release...

Could `tsize` be adapted in such a way that allows constant folding, rather than the compiler shortcuting the call? Genuine concern and possible use-case as there are a number of...
