Completely agree. Some language constructs that are "almost symbols" such as fn certainly works well to abbreviate, but for function names and types it feels outdated and hard to read. If a common function name is too long to spell out like iterate() then that is a candidate for sugaring out completely, not cutting in half.

Even in good C codebases that run static analysis, there are errors due to mixing up "memcpy()" and "memcmp()". UT4 is one example where this happened.
