I&amp;#x27;m not sure I understand your objection. Bytes and UTF8 characters are different things, and you can&amp;#x27;t abstract away the difference. There are also times, perhaps the majority of times, when you will need the byte count of a UTF8 string. That means you need at least two different length functions for strings and they need different names.&lt;p&gt;Shouldn&amp;#x27;t UTF8-specific things live in the utf8 namespace? Some programs won&amp;#x27;t need any string handling, after all, and it would be a waste to include code they never used.&lt;p&gt;Assuming you can allow the utf8 namespace as sensible, would you feel better if there was a RuneLen() function aliased to RuneCountInString()?&lt;p&gt;If you are that upset about it, then my suggestion is to explain your rationale and submit a patch[1] to provide the alias. It&amp;#x27;s not like it would be hard to code. Perhaps you might convince people and get it in the next release.&lt;p&gt;[1] &lt;a href=&quot;http://golang.org/doc/contribute.html&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;golang.org&amp;#x2F;doc&amp;#x2F;contribute.html&lt;/a&gt;</text><parent_chain><item><author>n1ghtm4n</author><text>Some thoughts after spending ~100 hours with Go.&lt;p&gt;- Function overloading is a major convenience that you will miss.
