We prefer to prevent using chained assignment (`T a = b = c = T();`) as this can lead to confusing code and subtle bugs. According to https://en.wikipedia.org/wiki/Assignment_operator_(C%2B%2B), C++ allows any arbitrary return type, so this is standard compliant. This could be re-assessed if/when we have an actual need for a behavior more akin to that of the C++ STL, for now this PR simply changes a handful of cases which were inconsistent with the rest of the codebase (`void` return type was already the most common case prior to this commit).
