 (e.g. changing ''puts("test")'' to ''fputs(STDERR, "test")'' would unexpectedly not print a terminating newline to STDERR (''fputs'' is an alias of ''fwrite''))
+==== Choice of Unix newline(\n) ====
+Some programming languages such as Java use a platform-specific or configurable newline https://docs.oracle.com/javase/6/docs/api/java/io/PrintStream.html#println%28%29
+Others, such as rust and golang, always use a unix newline.
+There have been some comments in favor of Unix newlines, and other comments in favor of PHP_EOL or configurable settings - e.g. https://externals.io/message/104545
+My reasons for unconditionally choosing the Unix newline are documented in the section [[#the_unix_newline_is_always_used|The Unix Newline is always used]].
+==== Should this be a language construct instead ====
+https://github.com/php/php-src/pull/3918#issuecomment-502012735
+<blockquote>
+Should't this be a language construct instead of a function, so it can be used without parenthesis just like echo or print?
+It would feel a little weird being able to do:
+<code php>
+echo 'hello world';
+print 'hello world';
+</code>
+... but not:
+<code php>
+puts 'hello world';
+</code>
+</blockquote>
+Adding this as a language construct (i.e. new statement type) is something I'd expect to be contentious, and this is deliberately NOT done. Adding a new keyword would
+  - Cause a larger BC break.
+  - Increase the complexity of the language specification and make the language a bit harder to learn; I'd prefer simplicity by using an ordinary global function in this case.
+  - Be impossible to polyfill (when brackets weren't added) for older php versions.
