I wouldn't say it's outlandish given my understanding of the
problem. The question is, does the pain justify the update? I
haven't run it against my code or any code really, but I can
see how someone is very good at making correct uses of the
implicit conversion.
Well that's the real problem here then, isn't it?
I wouldn't want this stuff "fixed" either, if I thought false
positives would outnumber useful warnings by 10,000 : 1.
However, I already *know* that's not the case, from my own tests.
But at this point I'm obviously not going to convince you, except
by compiling some concrete statistics on what got flagged in some
real code bases.
And this I plan to do (in some form or other), once `checkedint`
and/or the fix for DMD issue 259 are really ready. People can
make an informed decision about the trade-offs then.
