Embedded Scheme

Why the fuck did bash/vim have to make up their own languages instead of using a pre-existing one, like, say, Scheme? No, I have to waste time learning your toy language's syntax. Seriously, if Scheme was designed to be simple and elegant, why isn't it used more often as an embedded scripting language?

what kind of retard would want to use scheme as their shell or text editor?
scheme isn't used because real programmers laugh at functional languages
