Classes aren&amp;#x27;t supported natively by processors either, yet any number of OOP languages use them.&lt;p&gt;It&amp;#x27;s generally nice when you can do simple things with the language&amp;#x27;s built-in standard library.  I tend to prefer languages with more powerful standard libraries because it means that you can more easily move across codebases since they&amp;#x27;ll all be the same.  If commonly used data types like rationals, hashes, maps, strings, etc., aren&amp;#x27;t defined in the stdlib, then there&amp;#x27;ll be any number of different libraries to use them, and you&amp;#x27;ll have to potentially re-learn a lot of different unnecessary things when working on different codebases.</text><parent_chain><item><author>dmurray</author><text>&amp;gt; Why not introduce a primitive type &amp;quot;num&amp;quot; for arbitrary precision rational numbers instead?&lt;p&gt;Rationals aren&amp;#x27;t supported natively by processors, so there&amp;#x27;s no real need to handle this as a primitive instead of letting people to use a library for it.

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>usrusr</author><text>It&amp;#x27;s like building in special handling for a string type, exactly one instead of a catalog of library options.&lt;p&gt;I&amp;#x27;d say that would fit in quite well with the brand of minimalism that Go is representing, keep the language simple and provide builtins where more convenience is needed. The opposite kind of &amp;quot;minimalism&amp;quot; would be providing tools to allow libraries to define what other languages can only support as special builtins. C++ and Scala went down that road, they minimize builtins by empowering libraries to replace them. That&amp;#x27;s also a form of minimalism, but not the one chosen by Go.&lt;p&gt;Tangent: now I wonder wether Scala has inerited special handling for the (not special, but specially handled) string type it inherited from Java or if just reimplements those syntax extras in the standard library using implicits.</text><parent_chain><item><author>dmurray</author><text>&amp;gt; Why not introduce a primitive type &amp;quot;num&amp;quot; for arbitrary precision rational numbers instead?&lt;p&gt;Rationals aren&amp;#x27;t supported natively by processors, so there&amp;#x27;s no real need to handle this as a primitive instead of letting people to use a library for it.
