--- Comment #1 from Dlang Bot <[email protected]> --- @Zevenberge created dlang/phobos pull request #7339 "Improved error message when calling sum without a default value" mentioning this issue: - Improved error message when calling sum without a default value If sum() is called, it tries to find a default value by constructing it with 0 (e.g. float(0)). This works for numbers, but produces obscure errors if the value cannot be constructed this way (e.g. issue #19525). The error message now states that the problem lies in the default value and suggests to supply one instead. https://github.com/dlang/phobos/pull/7339 --
