But it does have an ASI hazard: break exit with "early" That might be what /be meant by: > I have some angst about loss of a hunk of code running "break L" up against " > with (E)\nS" where E is an expression and S is a statement and the two came > from a bone-fide with statement later in the unmangled source.
