I don't think that's necessarily true.  Take a look at
https://dlang.org/phobos/std_algorithm_mutation.html#copy

`TargetRange copy(SourceRange, TargetRange)(SourceRange source, TargetRange
target)`

Is copy an exception?

I recently asked about this convention at
https://github.com/dlang/druntime/pull/2264#pullrequestreview-143076892
