@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.
