--- Comment #4 from Nick Treleaven <n...@geany.org> --- (In reply to RazvanN from comment #2) > The safest and most restrictive solution would be to simply allow the > conversion only if the function is strongly pure, thus disallowing the > latter case, however, this may break code out there. The fix for issue 15660 is related, which was changed to only disallow the conversion with the -preview=fixImmutableConv switch: https://dlang.org/changelog/2.101.0.html#dmd.fix-immutable-conv That switch could be used to disallow this case too. --
