--- Comment #8 from berni44 <[email protected]> --- (In reply to David Nadlinger from comment #7) > Removal of "head const", i.e. the outer layer, is intentional. OK. In that case this is a Phobos bug. The solution would be to make peek remove "head const" on the given type und check if that's the type of the Variant. I've got too few experience on const, so I cannot fix this. I tried to add a small template which returns what it get's (just out of curiosity, if that could work). With this, peek could compare the type of the returned value to the value of the Variant. But this did not work out well. Partly, because the template needs to be given a value and not a type, partly because of inout gets in the way. I don't know if it's of much use, because this can be easily derived from the post above, but I created this unittest which currently does not pass but a corrected version of peek should pass: unittest { const int[] arr; Variant a = Variant(arr); assert(a.peek!(typeof(arr)) !is null); } --
