Avoid re-interning in `LateContext::get_def_path` The def path printer in `get_def_path` essentially calls `Symbol::intern(&symbol.to_string())` for simple symbols in a path. This accounts for ~30% of the runtime of get_def_path. We can avoid this by simply appending the symbol directly when available.
